Three new RPCs mirroring the existing deploy/teardown/status pattern:
- apply_topology(hydrated, version_hash) — long-timeout (600s) for
image pulls + compose up.
- teardown_topology(topology_id) — 300s timeout; enough for a
stubborn compose-down without hanging a heartbeat.
- get_topology_state() — short control-plane read for reconcile.
The per-call timeout swap uses the same trick as .deploy().
Step 5 of the agent <-> topology integration.
