feat(acp): hosts install a managed runtime over RPC, and mark agents whose program Orca provides (#29024)

Browse Source 
* feat(acp): hosts install a managed runtime over RPC, and mark agents whose program Orca provides

managedRuntime.status / managedRuntime.install / managedRuntime.cancel, negotiated by
managed-runtime.install.v1, act on the host that receives them, the one that runs the agent's
chats, with no workspace needed. A status read naming the revision it shows is a long-poll on its
own call-queue lane, so every client sees another's start, progress and outcome.
agentSession.agents marks an agent whose program Orca provides on that host.

* fix(runtime): install status says a copy outside Orca's runs only when a start would really run it

* fix(runtime): install status is pushed to subscribers instead of long-polled, and Cancel answers with the outcome

managedRuntime.subscribe {agent} sends a full snapshot on subscribe, then one
snapshot per install state change, and closes with the transport. It replaces
the managedRuntime.status long-poll and its slot registrations.
