Chunk 3 of the host-control-server stack: grow the broker op vocabulary
(PRD gap 3), starting with `list_live`, and invert `reconcile` onto it.
- broker: split the closed op vocabulary into mutation (`launch`/`teardown`,
carry a bottle id + static flags) and query (`list_live`, carries nothing
but its op name) kinds. `verify_request` now enforces a **strict schema**
(open question 1, resolved yes): unknown claim keys are rejected, a mutation
must name its bottle, and a query that smuggles any id/flag is refused.
- broker verb: `LaunchBroker.list_live` / `SubmitBroker.list_live` return the
backend's live source IPs; a backend enumeration failure is converted to the
single `BrokerUnavailableError` "live set unknown" signal. `DockerBroker`
enumerates its labelled containers; `StubBroker` derives from launches (or a
test override).
- host controller: `POST /broker/live` verifies a signed `list_live` token and
returns `{source_ips}`; `BrokerClient.list_live` is its drop-in client.
- reconcile: `OrchestratorCore.reconcile()` drops the `live_source_ips`
parameter and pulls the live set from the broker itself — the tell that the
orchestrator couldn't see the backend goes away. **Fail-safe**: if the broker
can't return an authoritative set the sweep is skipped, never run against an
empty/partial set (which would reap healthy rows). The `/reconcile` HTTP
contract + `OrchestratorClient.reconcile` become a bare trigger.
The macOS launcher's Apple-container enumeration stays for now; it becomes the
host controller's `list_live` when launch itself moves behind the broker (the
pulled-forward chunk 5, next in the stack).
Tests + pyright clean; pylint 10.0 on broker.
