feat: add Run Summary feature for session activity tracking

Implements a "what happened while you were away" view for sessions:
- Track significant events: session start/stop, respawn cycles, state changes,
  idle/working transitions, token milestones, auto-compact/clear, Ralph
  completions, AI check results, hook events, errors/warnings
- Stats dashboard: respawn cycles, peak tokens, active/idle time, issue counts
- Timeline view with color-coded severity and emoji icons
- Filter events by type (all/errors/warnings/respawn/idle)
- State stuck detection (warns when state unchanged for 10+ minutes)

Click the chart icon on any session tab to open the Run Summary modal.
