fix(supervise): docker gateway shares the one host DB (Step 2d)

The docker gateway container ran the supervise daemon but bind-mounted no
DB and set no SUPERVISE_DB_PATH — so the daemon wrote proposals to a
container-local, ephemeral SQLite file, disconnected from the host DB the
orchestrator (and now the operator, over HTTP) uses. Same split-DB bug
firecracker had; Dockerfile.gateway even documents the mount
(`/run/supervise/bot-bottle.db bind-mounted at run time`) that
ensure_running never provided.

Bind-mount the host DB dir into the gateway at /run/supervise and set
SUPERVISE_DB_PATH, so the daemon queues into the same file the
orchestrator container opens (its BOT_BOTTLE_ROOT bind-mount) and the
operator reaches over the control plane. One DB per host, shared by
bind-mounts — docker now on the exact same supervise path as firecracker.

-On the default macOS Apple Container backend, a bottle is an agent container on a host-only internal network plus a sidecar bundle 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 sidecar's internal-network IP, so HTTP/HTTPS traffic flows through the sidecar instead of direct egress. `bottle.git` / git-gate is intentionally deferred on this backend until a safe Apple Container key-delivery path exists.

+"""Docker-free agent-image builds for the Firecracker backend (PRD 0069 Stage 3).
+
+Agent Dockerfiles build **inside the persistent per-host infra VM**
+(`infra_vm.py`), which carries buildah (rootless, daemonless): no host Docker
+daemon, no root-equivalent `docker` group. The build runs over SSH against the
+infra VM and its rootfs streams back to the host, where the existing
+`mke2fs -d` path (`util.build_rootfs_ext4`) turns it into a bootable ext4.
+
+Building in the infra VM — rather than a throwaway builder VM — means there is
+one buildah image (`bot-bottle-infra`) and no contention for the orchestrator
+TAP. Tradeoff: an untrusted Dockerfile's `RUN` steps share the VM with the
+control plane + gateway (buildah `--isolation chroot` isn't a hard boundary) —
+the accepted single-VM blast-radius tradeoff, re-splittable into a disposable
+builder (booted from this same image on its own TAP) later.

+"""Launch flow for the macOS Apple Container backend — disabled (#385).
 
-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.
+This backend launched a per-bottle companion container (the egress /
+git-gate / supervise data plane) alongside the agent container, with the
+agent's proxy env pointed at the companion's host-only IP. That
+per-bottle-companion architecture was removed in the companion-container removal;
+the macOS backend will be re-enabled once it grows the consolidated
+per-host gateway the docker backend already uses.
+
+Until then, launching a macOS bottle fails closed. `prepare` / `status`
+/ cleanup still work.

+The launch path talks to the orchestrator over its HTTP control plane to

+"""The consolidated per-host gateway (PRD 0070).
+
+The core consolidation win: **one** persistent gateway per host, shared by
+every bottle, instead of a gateway per bottle. It's safe to share
+because the attribution invariant (source IP + identity token, see
+`registry`) lets the gateway attribute each request to the right bottle —
+so per-bottle policy lives in one long-lived process keyed on who's calling.
+
+`Gateway` is the backend-neutral lifecycle contract (mirrors `LaunchBroker`):
+ensure the single instance is up, report it, tear it down. `DockerGateway`
+is the docker implementation; a firecracker gateway VM slots in later.
+
+The defining behaviour is **idempotent singleton**: `ensure_running` starts
+the instance if absent and is a no-op if it's already up, so N bottle
+launches never spawn N gateways.

+
+The consolidated gateway serves every bottle from one process, so for each

+IP the attribution invariant makes unspoofable. This resolves that policy
+from the orchestrator's control plane (`POST /resolve`), keyed on the

+
+**Always fresh — no cache.** The resolver is called rarely enough that a
+round-trip doesn't matter, and correctness matters more than speed: every
+resolve reflects the orchestrator's *current* view, so a revocation, a
+policy change, or a bottle teardown the orchestrator knows about is honored
+immediately rather than lingering for a cache TTL. (If this ever becomes a
+hot path, add caching with orchestrator-driven invalidation — not a blind
+TTL.)
+
+**Fail-closed:** an unattributed client (the orchestrator answers `403`)
+resolves to `None`, and the caller (the egress addon, git-gate) must then
+deny — exactly as an unknown bottle should be treated. Orchestrator
+*errors* (unreachable / unexpected status) raise, so the caller can fail
+closed too rather than silently serving stale or empty policy.
+
+The resolved value is the policy blob the orchestrator stores verbatim; the
+consumer parses it (e.g. the egress addon's `load_config`). This module is

+  firewall.
+
+  **Our edge:** (1) *Isolation is the product, not a proxy.* OneCLI keeps the

+  unsandboxed — a hijacked agent behind OneCLI has full run of its host and can
+  exfil captured data through any allowed host. bot-bottle runs the agent inside
+  a kernel/VM-enforced sandbox, injects credentials across that same
+  out-of-process boundary, *and* clamps egress with pipelock — defense in depth
+  vs. a single network layer. (2) *Fleet + manifest model* with named agents,
+  skills, per-agent system prompts, multi-provider and multi-backend — OneCLI
+  has no equivalent. (3) *Trust posture:* OneCLI's managed tier reintroduces a
+  third-party credential custodian, whereas bot-bottle's OSS-runtime +
+  paid-control-plane split keeps custody inside the operator's own boundary —
+  the stronger story for the security-minded self-hoster. (4) *Runs inside your
+  network boundary — local/internal reach.* Because bot-bottle executes the
+  agent on your own host (homelab, corporate LAN, a Tailnet) and egress is a
+  manifest field, giving an agent *scoped* access to **internal** resources — a
+  private Gitea, a LAN database, a Tailscale node — is just another egress-route
+  line, not a networking project (the same move an operator already makes to
+  reach their Tailscale services). OneCLI's OSS core can self-host too, but it's
+  a credential *broker* for outbound API calls, not an agent runtime, and its
+  managed tier + 50+ integrations are oriented at public SaaS — it doesn't put
+  the agent behind your firewall for you. This is a reach advantage, distinct
+  from the isolation ones above, and it's a wedge cloud-first agent products

+"""Integration: two bottles share one gateway; source-IP attribution keeps
+their egress tokens *and* allowlists isolated (PRD 0070 multi-tenancy).
+
+The whole premise of the consolidation is one shared gateway for every
+bottle, isolated only by the unspoofable source IP. A single-bottle test
+can't catch cross-bottle token bleed or an allowlist leak — this brings up
+the real orchestrator + gateway and drives two bottles through the one
+gateway to prove each gets exactly its own token and its own routes.
+
+Gated on a reachable Docker daemon and builds the bundle image, so it runs
+with the other docker integration tests, not in unit CI. Uses the real
+fixed gateway/orchestrator names (that's what it's testing), so it can't run
+concurrently with a live per-host gateway; it points the orchestrator at a
+throwaway BOT_BOTTLE_ROOT for a clean registry and tears everything down.
