Re-enables the macos-container backend on the shared per-host orchestrator +
gateway, replacing the per-bottle companion container removed in #385. This is
the last backend in PRD 0070's roadmap.
Apple Container 1.0.0 forced three departures from the docker shape, each
verified against the live CLI (findings recorded in the networking spike):
- No `--ip`. The address is DHCP-assigned and knowable only once the container
runs, so the order inverts: gateway up -> run agent -> read its address ->
register. The identity token is minted by registration and therefore cannot
be in the agent's run-time env; it rides the proxy URL applied at
`container exec` time (bare `--env` names keep it off argv).
- No container DNS. The gateway can only be handed the control plane's IP, so
the orchestrator starts first and the gateway is pointed at its address.
- No `network connect`. Networks are fixed at run time, so the shared host-only
network is created up front; per-bottle networks would restart the gateway
on every launch and defeat the consolidation.
The agent runs with `--cap-drop CAP_NET_RAW`: Apple grants NET_RAW by default,
which would let an agent forge a neighbour's source address on the shared
segment. NET_ADMIN is already absent, so this closes the source-address half of
PRD 0070's attribution invariant.
Verified end-to-end on real Apple Container 1.0.0: both images build, the
control plane comes up healthy, the gateway reaches it by IP, and a registered
agent gets 200 for a host in its routes and 403 for one outside them. Bring-up
is idempotent — a second launch does not churn the singletons.

Completes the de-sidecar cleanup: no live code, test, current doc,
script, or nix file mentions or is named "sidecar" any more. Only the
dated PRD/research docs keep the term as historical record (agreed on
the #385 thread).
- Rename `sidecar_init.py`→`gateway_init.py` was done earlier; this pass
sweeps the remaining descriptive uses: the egress / git-gate / supervise
components are the gateway's *daemons*, the shared container is the
*gateway*, the old per-bottle container was the *companion container*.
- Rename `tests/integration/test_sidecar_bundle_image.py`→`test_gateway_image.py`
and its class; update `docs/ci.md` + `tests/README.md` for the renamed/
removed integration tests.
- `SIDECAR_PORTS` shell var in `scripts/firecracker-netpool.sh`→`GATEWAY_PORTS`.
Full unit suite green (bar the pre-existing `/bin/sleep`-missing env
errors in test_gateway_init); docker integration — gateway singleton,
broker, real two-bottle multitenant isolation, and the gateway-image
build — all pass.

The per-agent companion container (the egress/git-gate/supervise data
plane run once per bottle) is the pre-consolidation architecture. Remove
it and disable the backends that still depend on it, per the #385 thread.
- Delete `backend/docker/sidecar_bundle.py`; docker's live path uses the
consolidated shared gateway, not a per-bottle bundle.
- Disable the firecracker and macos-container backends: their `launch()`
fails closed (they launched a per-bottle companion; firecracker's
consolidated relaunch is #354, macos follows). Their `enumerate` return
empty and `cleanup` drop the companion-container discovery (firecracker
keeps VMM/run-dir cleanup).
- Fail-close both backends' `egress_apply` reload (it signalled the
per-bottle container); consolidated egress policy resolves per-request
against the orchestrator, so gateway-side apply is a follow-up.
- Rename `egress_sidecar_env_entries` → `egress_gateway_env_entries`,
`SIDECAR_PORTS` → `GATEWAY_PORTS`.
- Move the shared DockerBottlePlan fixture to `tests/unit/_docker_bottle_plan.py`;
delete tests for the removed launch paths; update cleanup/egress-apply tests.
Docker consolidated launch verified end-to-end (multitenant isolation
integration test passes). macos/firecracker are intentionally disabled.

Replace module-level apply_routes_change wrappers with a public
applicator singleton in each backend. Callers now work with the
EgressApplicator instance directly (applicator.apply_routes_change)
rather than through a function shim.
Pulls the duplicated apply_routes_change / validate_routes_content /
_routes_path logic into EgressApplicator (ABC) in backend/egress_apply.py.
DockerEgressApplicator and MacOSContainerEgressApplicator override the
single abstract _signal_bundle_reload method with their respective kill
commands. Module-level shims preserve the existing public API.
