fix(firecracker): reap legacy pre-split infra VM on cutover

The two-VM stop() only knew the new orchestrator/gateway config paths
(<infra>/{orchestrator,gateway}/config.json), so a host still running the
OLD single combined-VM (booted from <infra>/config.json on the orchestrator
link) kept it alive across the migration — and it held the orchestrator TAP,
so the first split boot died with "Open tap device failed: Resource busy"
(seen on the CI runner's bborchci0 pool).

stop() now also reaps that legacy singleton (both its drifted pidfile and any
firecracker whose --config-file is the legacy path), so the cutover is
self-healing with no manual per-host teardown. Scoped to the legacy infra
config path, so pool agent VMs are untouched.

-"""Per-backend bottle factories.
+"""The bottle-backend package: abstract contract + backend selection.
 
-A bottle is a running, isolated environment with claude inside. Each
-backend exposes five methods:
+Thin by design — nothing framework-heavy is imported at package init, so
+importing any `backend.*` submodule (e.g. `backend.docker.util`) doesn't drag
+the manifest / egress / git-gate framework into memory. The public names are
+re-exported lazily:
 
-  prepare(spec, stage_dir=...) -> BottlePlan
-      Resolves names, validates host-side prerequisites, and writes
-      scratch files. No remote/runtime resources are created yet.
-      Safe to call before the y/N preflight.
+  * the abstract contract (`BottleBackend`, `BottleSpec`, `Bottle`, …) lives in
+    `backend.base`;
+  * backend selection / enumeration (`get_bottle_backend`,
+    `enumerate_active_agents`, …) in `backend.selection`;
+  * the concrete backends and the freeze helpers in their own submodules.
 
-  launch(plan) -> ContextManager[Bottle]
-      Brings up the container (or VM, or remote machine), provisions
-      it, yields a Bottle handle, and tears everything down on exit.
-
-  prepare_cleanup() -> BottleCleanupPlan
-      Enumerates orphaned resources left behind by previous bottles
-      (containers, networks, ...). Idempotent; no side effects.
-
-  cleanup(plan) -> None
-      Actually removes everything described by the cleanup plan.
-
-  enumerate_active() -> Sequence[ActiveAgent]
-      Return every currently-running bottle on this backend, with
-      enough metadata for callers (CLI `list active`, dashboard
-      agents pane) to render a row.
-
-Selection is driven by `--backend` on `start` or BOT_BOTTLE_BACKEND
-(env var). When neither is set, compatible macOS hosts default to
-`macos-container`; Linux hosts with KVM default to `firecracker`;
-otherwise `docker`. Per PRD 0003 the manifest does not carry a
-backend field; the host picks.
+`from bot_bottle.backend import X` resolves X on first access via `__getattr__`
+and caches it at package level, so existing call-sites (and
+`patch.object(backend_mod, X, …)`) keep working.

-`Gateway` is the backend-neutral lifecycle contract (mirrors `LaunchBroker`):

-is the docker implementation; a firecracker gateway VM slots in later.

 Attribution is by the agent VM's guest IP, unspoofable by construction: the
 /31 point-to-point TAP + the `bot_bottle_fc` nft table ensure only the
 expected VM can source-IP that address.

-"""The per-host infra container for the macOS backend (PRD 0070).
+"""The per-host control plane + gateway 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.
+Two Apple containers — the orchestrator (control plane) and the gateway (data
+plane) — split now that #469 got the DB off the data plane. The single-container
+model existed only because two Apple-Container guests writing one `bot-bottle.db`
+over virtiofs would race incoherent `fcntl` locks; with the data plane no longer
+opening the DB at all, only the orchestrator does, so the split is safe.
 
-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.
+  * `bot-bottle-mac-orchestrator` — the lean control plane. Joins the host-only
+    **control network** (`bot-bottle-mac-control`) only. Sole opener of the
+    container-only DB volume; holds the signing key. The host CLI reaches it at
+    its control-network address; the gateway reaches it there too.
+  * `bot-bottle-mac-infra` — the gateway data plane. Triple-homed: the NAT
+    egress network (route out), the host-only agent network (agents + CLI reach
+    the gateway), and the control network (reach the orchestrator by IP — Apple
+    has no container DNS). Holds the mitmproxy CA + the `gateway` JWT.
 
-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.
+Agents sit on the agent network only, never the control network, so they have no
+route to the control plane (the L3 block, not just the JWT).

+`Egress` builds a bottle's egress plan at launch: resolve the manifest's egress

+plant the exfil canary. The service also resolves the launch-time token values
+and the agent/gateway env entries the backend injects. The runtime enforcement
+(the mitmproxy addon) lives in `bot_bottle.gateway.egress.addon*`.
