didericis-claude 2f45f5afec feat(docker): consolidate to single infra container under gateway_init supervise tree
Collapses the two-container Docker model (gateway + orchestrator) into one
bot-bottle-infra container, matching the macOS and Firecracker backends.

- Dockerfile.infra: now a shared gateway+orchestrator base (COPY bot_bottle
  from orchestrator build, no CMD override)
- Dockerfile.infra.fc: new Firecracker-specific layer (buildah/crun/netavark)
- gateway_init: adds orchestrator daemon with _OPT_IN_DAEMONS gating so it
  only starts when BOT_BOTTLE_GATEWAY_DAEMONS explicitly includes it
- orchestrator/lifecycle: OrchestratorService manages one infra container;
  builds orchestrator (intermediate) then infra; live source bind-mounted at
  /bot-bottle-src with PYTHONPATH so the subprocess uses the checkout
- backend/consolidated_util: extracts provision_bottle + teardown_consolidated
  shared across all three backends; removes duplication in docker/fc/macos
  consolidated_launch modules
- firecracker/infra_vm: builds four images (orchestrator→gateway→infra→infra.fc)
- All unit tests updated and passing (1878 tests)
- PRD status: Draft → Active

"""Consolidated bottle launch sequence for the Firecracker backend
(PRD 0070, Stage B).
The shared gateway + orchestrator control plane run in a single persistent
per-host **infra VM** (`infra_vm.py`), not Docker containers. Agent VMs reach
the gateway's egress / supervise / git-http ports at the infra VM via a
PREROUTING DNAT on their own host-side TAP IP (see
`scripts/firecracker-netpool.sh`), and the host CLI reaches the control plane
over HTTP at the infra VM's guest IP.
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.
Sequence:
1. ensure the infra VM (control plane + gateway) is up (a singleton — a
prior launcher may already have booted it);
2. register the bottle by its guest IP (attribution key) → bottle id +
identity token;
3. provision its git-gate repos/creds into the gateway VM (over SSH);
4. fetch the shared gateway CA for the provisioner to install in the rootfs.
The TAP slot allocation, rootfs build, and VM boot are the caller's job.
