refactor(orchestrator): rename Sidecar -> Gateway for the consolidated data plane

Retire "sidecar" for the consolidated per-host path (PRD 0070 naming
decision): the orchestrator is the umbrella/control plane, and the
egress/git/supervise data-plane unit it runs is the "gateway".

- git mv sidecar.py -> gateway.py and the two integration + one unit test
  files; DockerSidecar->DockerGateway, Sidecar->Gateway,
  SidecarError->GatewayError, SIDECAR_*->GATEWAY_*, ensure_sidecar->
  ensure_gateway, sidecar_status->gateway_status, container name
  bot-bottle-orch-sidecar->bot-bottle-orch-gateway.
- Prose rename across broker/registry/egress/policy_resolver + PRD 0070.
- Preserved: the image name bot-bottle-sidecars, the
  BOT_BOTTLE_SIDECAR_IMAGE env var, Dockerfile.sidecars, and PRD 0069's
  own stage-name cross-references (that doc still uses "sidecar").

No behavior change. Full unit suite green (1679 tests; the 13
test_sidecar_init /bin/sleep errors are pre-existing NixOS-local noise).

-1. **Dev-harness core** ✅ — SQLite registry (runtime state) + fail-closed
-   attribution (source IP + identity token) + the HTTP control plane.
-2. **Launch lifecycle + broker contract** ✅ — `launch_bottle` /
-   `teardown_bottle` + the signed, structured `LaunchBroker` request
-   (HS256 JWT, static ids/flags only, provenance-verified, fail-closed),
-   with a stub broker for the harness and registry rollback on failure.
-3. **Docker launch broker** ✅ — the first real broker: `docker run` / `rm`
-   per bottle, built only from the request's static fields; proves the
-   `BottleBackend` seam on the cheapest backend.
-
-   **The consolidated-sidecar arc** (the core consolidation win — one
-   persistent sidecar shared by all bottles instead of one per bottle):
-
-4. **Sidecar — lifecycle** ✅ — the idempotent-singleton `Sidecar` /
-   `DockerSidecar` (ensure-running is a no-op when already up, stop is
-   idempotent); one container per host.
-5. **Sidecar — build the real bundle image** ✅ — the orchestrator builds
-   the `bot-bottle-sidecars` bundle from `Dockerfile.sidecars` when missing
-   and launches *that* (not a placeholder) as the singleton.
-6. **Sidecar — source-IP-keyed multi-tenant config** — the functional
-   core: the per-bottle CA / egress routes / git-gate keys / policy, today
-   baked per bottle, become **multi-tenant and selected by the verified
-   source IP**, with per-bottle add/remove (live reload) on launch/teardown
-   through the control plane. Until this lands, one shared instance can't
-   serve multiple bottles' distinct policies.
-7. **Sidecar — route agent bottles through it** — wire each agent bottle's
-   egress/git to the shared sidecar (DNAT / network) instead of a per-bottle
-   bundle.
-
-   **Remaining backends** (docker done above; the rest against the proven
-   dev-harness):
-
-8. **Firecracker broker + sidecar** — the real work: the shim + VM-to-VM
+1. **Docker orchestrator** — nearly free (the gateway bundle is already
+   containers; collapse N bundles into one persistent container). Proves
+   consolidation + the `BottleBackend` seam with the least moving parts.
+2. **Firecracker orchestrator** — the real work: the shim + VM-to-VM
    routing (host forwards `bbfcN` → orchestrator TAP; the nft table grows
-   forward rules where today it drops all non-DNAT egress).
-9. **macOS (Apple container)** — last (container-to-container networking).
