FN-8864: add durable agent activity stream
Add a persisted, project-scoped agent activity feed with query and live delivery surfaces.
- Store sequenced, attributed activity events with privacy-safe metadata and retention.
- Emit activity across agents, workflow execution, reviews, approvals, merges, and recovery.
- Provide paginated API history and resilient SSE tailing with coverage and documentation.
- Renumber the activity migration to 0049 after reconciling main’s 0048 GitHub check-state migration.
