feat: track Ralph Wiggum loops and todo lists in Claude sessions

Add InnerLoopTracker to detect and expose internal Claude Code state
running inside claudeman sessions by parsing terminal output patterns.

Detection patterns:
- Completion phrases: <promise>PHRASE</promise>
- Todo items: checkbox format, indicator icons, status parentheses
- Loop status: cycle counts, elapsed time, start/completion

New features:
- Inner state panel UI (collapsible, below session tabs)
- SSE events: innerLoopUpdate, innerTodoUpdate, innerCompletionDetected
- API endpoint: GET /api/sessions/:id/inner-state
- State persistence to ~/.claudeman/state-inner.json
