fix(docker): use run_docker in docker_exec, docker_cp, verify_agent_image

The rebase onto lazy-backend-imports converts existing helpers (image_exists,
container_exists, etc.) to run_docker; the three new functions added in this
branch still called subprocess.run directly. Switch them over for consistency.

 ## Architecture
 
-On the default macOS Apple Container backend, a bottle is an agent container on a host-only internal network plus a gateway attached to both that internal network and a NAT egress network. The agent gets HTTP(S)_PROXY and CA bundle env vars pointing at the gateway's internal-network IP, so HTTP/HTTPS traffic flows through the gateway instead of direct egress. `bottle.git` / git-gate is intentionally deferred on this backend until a safe Apple Container key-delivery path exists.

-"""Prebuilt infra-VM rootfs, pulled as an artifact (PRD 0069 Stage 2).
-
-The Firecracker infra VM boots a fixed rootfs (orchestrator control plane +
-gateway + buildah, control-plane init as PID 1) that does not vary per launch —
-the per-boot bits (authorized_keys, guest IP) ride the kernel cmdline, so one
-rootfs boots on any host. Instead of building that rootfs on the launch host
-with Docker, we build it **off-host** and publish it as a versioned, ready-to-
-boot ext4 (gzip-compressed) to a Gitea **generic package**; the launch host
-downloads + verifies + boots it. No Docker, no image tooling on the launch
-host — just an HTTP fetch and gunzip.
-
-  publish (off-host, see publish_infra.py):
-    docker build -> rootfs dir -> mke2fs -> gzip -> PUT generic package
-  pull (this module, launch host):
-    GET .../rootfs.ext4.gz (+ .sha256) -> verify -> gunzip -> boot
-
-The artifact **version** is a content hash of everything baked into the rootfs
-(the shipped bot_bottle package, the three Dockerfiles, and the init), so a
-launch host always pulls the artifact matching its code and a content change
-can't silently boot a stale rootfs. A checksum mismatch fails closed.
-
-Set `BOT_BOTTLE_INFRA_BUILD=local` to skip the pull and build the rootfs
-locally with Docker (dev iteration on the Dockerfiles) — see `infra_vm`.

-"""Consolidated bottle launch sequence for the macOS backend (PRD 0070).
-
-The docker backend allocates a free address, pins the agent to it with
-`--ip`, registers it, *then* starts the agent — registration precedes launch
-because the pinned address is known up front.
-
-**Apple Container 1.0.0 has no `--ip`.** The `--network` flag takes only
-`<name>[,mac=…][,mtu=…]`; the address is assigned by vmnet's DHCP and is
-knowable only once the container is running. So the macOS order inverts:
-
-    ensure_gateway()  ->  caller starts the agent  ->  register_agent(source_ip)
-
-That is why this module exposes two functions where docker has one — the
-caller has to start the agent in between. `ensure_gateway` runs first because
-the agent's proxy env needs the gateway's address at `container run` time; the
-agent's *own* address (the attribution key) only exists afterwards.
-
-The control plane and the gateway are one **infra container** here (see
-`infra`), so `gateway_ip` and the control-plane host are the same address.
-
-The consequence for the identity token: it is minted by registration, i.e.
-*after* the agent container exists, so it cannot be baked into the run-time
-env the way docker's compose spec does. It is delivered at `container exec`
-time instead — see `bottle.MacosContainerBottle`.
-
-That delivery is load-bearing, not a nicety: `/resolve` requires a matching
-`(source_ip, identity_token)` pair and fail-closes with no source-IP-only
-fallback (#366). So egress that does not carry the token is denied — which is
-the safe direction, and is why the agent's init process is a bare `sleep` and
-every real command arrives through `container exec`.

-"""The per-host infra container for the macOS backend (PRD 0070).
-
-A single persistent Apple container that runs BOTH the orchestrator control
-plane and the gateway data plane — the macOS analogue of the Firecracker infra
-VM (`backend/firecracker/infra_vm.py`), not the docker backend's two separate
-containers.
-
-Why one container, not two: Apple Containers are lightweight VMs, each with its
-own kernel. The docker backend runs the orchestrator and gateway as two
-containers safely because they share the host kernel, so their concurrent
-writes to the one `bot-bottle.db` (the orchestrator's registry + the gateway
-supervise daemon's queue) are serialized by coherent `fcntl` locks. Across two
-*guest* kernels sharing a virtiofs-mounted DB those locks are not coherent, and
-concurrent writers can corrupt the file. Firecracker solved this by putting
-both services in one guest with the DB on a device only that guest mounts; this
-does the same with Apple primitives.
-
-Two consequences fall out of the single container, both simplifications:
-
-- **No DNS dance.** The control plane and the gateway daemons reach each other
-  over `127.0.0.1`, so nothing depends on Apple's (absent) container DNS and
-  there is no orchestrator-before-gateway ordering to get right.
-- **The DB is never host-shared.** It lives on a container-only volume, so no
-  host process opens the live file. The host CLI reaches registry + supervise
-  state through the control-plane HTTP surface (`cli/supervise.py` already uses
-  `OrchestratorClient`), exactly as it does for firecracker.
-
-The control-plane source is bind-mounted (like the docker orchestrator), so a
-code change takes effect on the next launch without an image rebuild; the
-gateway daemons are baked in the gateway image and rebuild through its own
-digest check.

+"""Launch flow for the macOS Apple Container backend.
 
-The agent container attaches to the **shared host-only gateway network** and
-proxies egress through the one per-host gateway, replacing the per-bottle
-companion container removed in #385.
-
-The order differs from docker's, forced by Apple Container 1.0.0 having no
-`--ip` (see `consolidated_launch`): the agent is started *before* it is
-registered, because its DHCP-assigned address — the attribution key — does not
-exist until then.
-
-    gateway up -> run agent -> read its IP -> register it -> provision
-
-Two things follow from that inversion:
-
-- The **identity token** is minted by registration and so cannot be in the
-  agent's run-time env; it rides the proxy URL applied at `container exec`
-  time (`bottle.MacosContainerBottle`). `/resolve` requires it (#366), so
-  egress without it is denied — hence the bare `sleep` init: every real agent
-  command goes through exec and therefore carries the token.
-- The agent is run with `--cap-drop CAP_NET_RAW`. Apple Container grants
-  NET_RAW by default, which would let an agent open a raw socket and forge a
-  neighbour's source address on the shared segment. NET_ADMIN is already
-  absent (the agent cannot change its own address or route), so dropping
-  NET_RAW is what closes the source-address half of PRD 0070's invariant:
-  "a packet's source address, as seen by the orchestrator, provably identifies
-  the originating bottle." The identity token is the other half — an attacker
-  would need to forge the address *and* steal the token — but the invariant is
-  a stated precondition of consolidation, so it is enforced on its own terms
-  rather than left to the token.
+This backend keeps the explicit proxy-env enforcement model for v1:
+the agent container is attached only to a host-only Apple Container
+network, while the sidecar bundle is attached to a NAT network first
+and the host-only network second. The sidecar's host-only IP is
+discovered from `container inspect` and stamped into the agent's
+HTTP_PROXY / HTTPS_PROXY env vars.

 ## Summary
 
 Make the Firecracker backend depend on **firecracker + KVM only**, removing
 Docker from the host. Two moves get us there: run the **sidecar bundle as a
 persistent, per-host service** (eventually a Firecracker VM) instead of a
-per-bottle container, and **provision rootfs images without a host Docker
-daemon** — pull the fixed images (orchestrator/gateway/infra) from an OCI
-registry and unpack them daemonlessly, and build user Dockerfiles in an in-VM
-builder. The images are still *built* with Docker, but off the launch host
-(CI / a publish step) and pushed to the registry; the launch host only pulls.

 Can ship as a container first (quick resource/ops win) and become a VM in
 Stage 4.
 
-### Stage 2 — Fixed rootfs prebuilt + pulled as an artifact (no host Docker)
+### Stage 2 — Fixed images built with nix (no Docker)
 
-The one fixed image the Firecracker backend needs at launch — the combined
-**infra** rootfs the infra VM boots (orchestrator control plane + gateway +
-buildah, with the control-plane init as PID 1) — is **prebuilt end-to-end off
-the launch host and published as a versioned, ready-to-boot ext4 artifact**.
-The launch host **downloads the `.ext4` and boots it directly** — no
-`docker build`, no `docker export`, no `mke2fs`, no image tooling at all.
-
-This is possible because the infra rootfs is already **host- and
-bottle-agnostic**: the per-boot bits (authorized_keys, guest IP) arrive on the
-**kernel cmdline**, not in the rootfs (see `build_base_rootfs_dir`). So one
-published ext4 boots on any launch host.
-
-- **Artifact.** `rootfs.ext4` + a `rootfs.ext4.sha256`, published as a Gitea
-  **generic package** (`bot-bottle-firecracker-infra/<tag>`) — generic packages take
-  arbitrary large binaries (no attachment size cap / file-type allowlist that
-  release attachments impose). The matching `vmlinux` kernel can ship the same
-  way, so the whole VM is fetchable.
-- **Pull.** The launch host `GET`s
-  `…/api/packages/<owner>/generic/bot-bottle-firecracker-infra/<tag>/rootfs.ext4` (+
-  `.sha256`) for its pinned tag, verifies the checksum, caches it under the
-  tag, and attaches it as the infra VM's root disk. Host prerequisite is an
-  HTTP client — nothing else. Public packages need no auth to pull; a token
-  with `read:package` covers a private instance.
-- **Registry.** The artifact base URL + owner are configurable, defaulting to
-  this deployment's Gitea (`https://gitea.dideric.is` / `didericis`);
-  overridable via env for other deployments / air-gapped mirrors.
-- **Versioning.** A pinned tag bumped when the infra rootfs contents change
-  (bot_bottle's shipped files, the base deps, or the init), so a launch host
-  pulls the artifact matching its code and a content change can't silently
-  boot a stale rootfs. A checksum mismatch fails closed.
-- **Publish.** A `publish` step (CLI subcommand / CI job) runs the full
-  pipeline **on a build/CI host** — `docker build` the three Dockerfiles →
-  export → inject guest boot → `mke2fs` → upload the `.ext4` + `.sha256`.
-  Building still uses Docker, but never on the launch/runner host, which is
-  the one #348 needs unprivileged.
-- **Dev escape hatch.** An explicit opt-in still builds the rootfs locally
-  with Docker (for iterating on the Dockerfiles without a publish
-  round-trip); it is never the default path.
-
-Removes Docker from the launch host entirely for the fixed image, and the
-launch host needs no OCI/rootfs tooling — just fetch + boot. The build-time
-cache / build-time-egress open problems a from-scratch build would face don't
-arise: the launch host never builds, it downloads a finished disk.
+The images bot-bottle *ships* — the sidecar, the agent base, and the builder
+(Stage 3) — are built declaratively with nix (`nixos-generators` /
+`make-ext4-fs` / `pkgs.dockerTools` for the rootfs), producing an ext4 or
+tar with correct ownership. Removes Docker for everything we own and gives
+the rootless-rootfs correctness (#347) for free on these images.

@@ -358,111 +358,3 @@ the Apple Container-specific constraints directly:
 
 Do not implement the backend as a direct clone of Docker Compose
 service aliases. That assumption failed in this run.
-
-## Addendum: consolidated-gateway findings (2026-07-17, PRD 0070)
-
-Re-tested on Apple Container 1.0.0 while porting the backend to the
-per-host consolidated gateway (#351). The two-network shape above still
-holds; these are the additional constraints that shaped the port, each
-verified against the live CLI on this host.
-
-### No static IP for a container
-
-`container run --network` accepts only
-`<name>[,mac=XX:XX:XX:XX:XX:XX][,mtu=VALUE]`. There is no `--ip`. The
-address comes from vmnet's DHCP and is knowable only after the container
-is running:
-
-```console
-$ container run --name a --network bb-net --detach alpine sleep 900
-$ container inspect a | jq -r '.[0].status.networks[0].ipv4Address'
-192.168.128.3/24
-```
-
-Consequence: the docker backend's "allocate a free IP -> pin it with
-`--ip` -> register -> launch" order cannot be reproduced. macOS inverts
-it to "launch -> read the assigned address -> register". The identity
-token therefore cannot be in the agent's run-time env (registration mints
-it after the container exists) and is delivered at `container exec` time.
-
-### Networks are fixed at run time
-
-There is no `container network connect`; `container network` exposes only
-`create`, `delete`, `list`, `inspect`, `prune`. A network cannot be
-attached to a running container, so a *persistent* shared gateway rules
-out per-bottle networks — they would force a gateway restart per launch.
-One shared host-only network, created up front, is the only shape that
-keeps the gateway a singleton.
-
-### No container DNS
-
-Containers cannot resolve each other by name; the host-only network's
-resolver refuses the query:
-
-```console
-$ container exec agent nslookup gw
-;; connection timed out; no servers could be reached
-$ container exec agent cat /etc/resolv.conf
-nameserver 192.168.128.1
-```
-
-Consequence: the gateway is handed the control plane's **IP**, not a
-container name as on docker. That forces the startup order
-orchestrator -> read its address -> gateway.
-
-### The host can reach the host-only network directly
-
-```console
-$ container inspect c | jq -r '.[0].status.networks[0].ipv4Address'
-192.168.128.2/24
-$ curl -s http://192.168.128.2:8099/i
-ok
-```
-
-So no `--publish` hop is needed: the host CLI and the gateway use the
-same control-plane URL. Docker needs `--publish 127.0.0.1:...` plus a
-separate internal URL for the same job.
-
-### CAP_NET_RAW is granted by default — and matters for attribution
-
-Apple grants NET_RAW but not NET_ADMIN. The agent therefore cannot change
-its own address or route:
-
-```console
-$ container exec agent ip addr add 192.168.128.99/24 dev eth0
-ip: RTNETLINK answers: Operation not permitted
-$ container exec agent ip route replace default via 192.168.128.2 dev eth0
-ip: RTNETLINK answers: Operation not permitted
-$ container exec agent grep CapEff /proc/self/status
-CapEff:	00000000a80425fb        # bit 13 (NET_RAW) set, bit 12 (NET_ADMIN) clear
-```
-
-But NET_RAW permits raw sockets, i.e. source-address forgery against
-neighbours on the shared segment — directly against PRD 0070's invariant
-("a packet's source address, as seen by the orchestrator, provably
-identifies the originating bottle"). `--cap-drop CAP_NET_RAW` closes it:
-
-```console
-$ container run --cap-drop CAP_NET_RAW ... alpine
-$ container exec nr grep CapEff /proc/self/status
-CapEff:	00000000a80405fb        # bit 13 cleared
-$ container exec nr ping -c1 192.168.128.2
-ping: permission denied (are you root?)
-```
-
-The agent is run with `--cap-drop CAP_NET_RAW` for this reason.
-
-### `container exec` inherits run-time env, and `--env` overrides it
-
-```console
-$ container run --name e --env FOO=from_run --detach alpine sleep 120
-$ container exec e sh -c 'echo $FOO'
-from_run
-$ container exec --env FOO=from_exec e sh -c 'echo $FOO'
-from_exec
-```
-
-This is what makes exec-time identity-token delivery work: the token-less
-proxy URL baked in at launch is superseded by the token-bearing one at
-exec. Bare `--env NAME` (inherit from the parent process) keeps the token
-value off argv.
