didericis-claude 904ed2ef2f feat(orchestrator): host control server transport (#468)
Chunk 1 of the host-control-server stack: close the PRD's **transport**
gap. Today LaunchBroker.submit(token) is an in-process method call from
OrchestratorCore; this makes it a real out-of-process service reached
over HTTP.

- host_server.py: the host control server. A pure dispatch() (POST
  /broker verifies a signed token via the existing verify_request +
  _launch/_teardown path, GET /health) wrapped by a thin http.server
  adapter, mirroring orchestrator/server.py. Only the signed token
  crosses the wire; provenance/schema failures are fail-closed 401s that
  never touch the backend, a backend launch failure is a 502.
- broker_client.py: BrokerClient — a drop-in submit(token) that POSTs the
  signed token to the host controller. A 401 re-raises as BrokerAuthError
  so the launch path's rollback is identical local or remote.
- broker.py: SubmitBroker Protocol — the one method OrchestratorCore
  depends on, satisfied by both LaunchBroker and BrokerClient, so the
  core is unchanged (service.py annotation only).
- __main__.py: wire `--broker http` behind the shared-secret env var
  (BOT_BOTTLE_BROKER_SECRET, hex) — a chunk-1 stopgap the durable
  TrustDomain key (chunk 2, #476) replaces.

Tested: pure-dispatch cases, BrokerClient with HTTP mocked, and a
real-socket sign -> POST -> verify -> act round-trip (incl. fail-closed
forged token). pyright clean; pylint 9.86.

"""Run the orchestrator control plane as a plain process (PRD 0070 dev-harness).
python -m bot_bottle.orchestrator [--host H] [--port P] [--db PATH]
The PRD sequences the orchestrator as a plain-process dev-harness first, so
the consolidation core (registry + attribution + HTTP control plane + live
reload) can be exercised with fast iteration, decoupled from any VM /
container packaging. Wrapping this exact service in a backend-native unit
(docker container, then Firecracker VM) comes later.
