pyr0ball 7e14f9135e feat: Notation v0.1.x scaffold — full backend + frontend + tests
FastAPI backend (port 8522):
- Session lifecycle: POST /session/start, DELETE /session/{id}/end, GET /session/{id}
- SSE stream: GET /session/{id}/stream — per-subscriber asyncio.Queue fan-out, 15s heartbeat
- History: GET /session/{id}/history with min_confidence + limit filters
- Audio: WS /session/{id}/audio — binary PCM ingestion stub (real inference in v0.2.x)
- Export: GET /session/{id}/export — downloadable JSON session log
- ContextClassifier background task per session (CF_VOICE_MOCK=1 in dev)
- ToneEvent SSE wire format per cf-core#40 (locked field names)
- Tier gate: CFG-LNNT- prefix check, 402 for paid features

Vue 3 frontend (port 8521, Vite + UnoCSS + Pinia):
- NowPanel: affect-aware border tint, subtext, prosody flags, shift indicator
- HistoryStrip: horizontal scroll, last 8 events with affect color
- ComposeBar: start/stop session, SSE connection lifecycle
- useToneStream: EventSource composable
- useAudioCapture: AudioWorklet → Int16 PCM → WebSocket (v0.1.x stub)
- audio-processor.js: 100ms chunk accumulator in AudioWorklet thread
- Respects prefers-reduced-motion globally

26 tests passing, manage.sh, Dockerfile, compose.yml included.
