Implement the ability to replay recorded agent sessions through the existing timeline UI. Sessions are enriched with AgentState snapshots stored in SQLite (schema v3 migration), and a new REST endpoint serves replay events. The client orchestrates replay via ReplayManager which pauses the live WebSocket, loads recorded events into StateStore, and drives the Timeline's existing playback controls. Changes: - Shared: Add ReplayTimelineEvent type extending RecordedTimelineEvent with AgentState - Server: Schema v2->v3 migration adding agent_state_json column to timeline tables - Server: SessionRecorder now serializes stripped AgentState per event - Server: GET /api/sessions/:id/replay-events endpoint - Client: ReplayManager orchestrates enter/exit replay flow - Client: StateStore.enterReplayMode/exitReplayMode for state isolation - Client: WsClient.pause/reconnect for non-destructive WS lifecycle - Client: Timeline recording replay mode with REPLAY badge and exit button - Client: Session history panel Replay button per session row - Client: Escape key exits replay mode Co-Authored-By: Claude Opus 4.6 (1M context) <[email protected]>
