feat: add use-case session management, analysis algorithms, and REST API (v0.5.0)

Browse source 
- Add session layer with UseCaseSession, SessionRun, SessionManager
  for use-case driven telemetry analysis (shift points, track mapping)
- Add analysis module with shift point detection (gear RPM ranges,
  upshift events, recommended shift RPM) and track map reconstruction
  (spline-aligned interpolation for center line from boundary runs)
- Add 9 REST API endpoints for session CRUD, run management, and
  analysis triggers under /api/sessions/*
- Add RecordingManager with always-on ring buffers (5 min, 18k frames)
  replacing raw binary file dumps
- Wire SessionManager in main.rs with Arc<Mutex> shared state
- Add TelemetryFrame Serialize derives for JSON API output
- Fix stop_recording race: hold active lock across flush I/O
- Fix flush: separate ring buffer lock from JSON serialization
- Fix flush failure propagation: errors prevent Stopped status
- Add data_truncated flag on SessionRun for ring buffer wrap detection
- Deduplicate gear_display into shared free function
- Deduplicate session_display into closure
- Mutex poisoning recovery on all session API handlers
