fix(opencode): announce locally started sessions to the mobile live list

[iscekic]

What changed

• CLI sessions that start locally (kilo run, TUI) now appear in the live list when their first turn opens.
• A locally started session leaves the live list when it is disposed.
• A completed turn does not remove the session from the live list.
• Repeated turns on one session add no duplicate live-list entry.
• The CLI does not announce a session when remote is disabled.
• A first turn that races bootstrap remote enable waits for enable and still announces.
• A failed announce rolls the attach back and retries on the next turn.
• A failed detach rolls back so the session stays in the live list.

Why

The live list in the app is fed by the relay registry for each connection.
The registry is built only from attached-session ids on the remote heartbeat.
The CLI attached a remote session only from the app-spawned create_session path.
Locally created sessions connected and sent heartbeats but never announced.
They never appeared in the live list.

Verification

• Driver checks: 3 checks passed after round 2.
• backend: no changed service.
• cli: test:ci failed only on files that also fail on clean main (pre-existing); advisory.

Notes for the reviewer

Dispose of an unowned id is a no-op.
This covers an app-spawned session that exit_cli already detached.
