fix(run): pass directory to event.subscribe for session-scoped events

The SSE event stream subscription was missing the directory parameter,
causing the OpenCode server to only emit global events (heartbeat,
connected, toast) but not session-scoped events (session.idle,
session.status, tool.execute, message.updated, message.part.updated).

Without session events:
- hasReceivedMeaningfulWork stays false (no message/tool events)
- mainSessionIdle never updates (no session.idle/status events)
- pollForCompletion either hangs or exits for unrelated reasons

Fix: Pass { directory } to client.event.subscribe(), matching the
pattern already used by client.session.promptAsync().

Also adds a stabilization period (10s) after first meaningful work
as defense-in-depth against early exit race conditions.
