feat: Complete ADR-001, ADR-009, ADR-012 implementations with zero mocks

ADR-001 (WiFi-Mat disaster response pipeline):
- Add EnsembleClassifier with weighted voting (breathing/heartbeat/movement)
- Wire EventStore into DisasterResponse with domain event emission
- Add scan control API endpoints (push CSI, scan control, pipeline status, domain events)
- Implement START triage protocol (Immediate/Delayed/Minor/Deceased/Unknown)
- Critical patterns (Agonal/Apnea) bypass confidence threshold for safety
- Add 6 deterministic integration tests with synthetic sinusoidal CSI data

ADR-009 (WASM signal pipeline):
- Add pushCsiData() with zero-crossing breathing rate extraction
- Add getPipelineConfig() for runtime configuration access
- Update TypeScript type definitions for new WASM exports

ADR-012 (ESP32 CSI sensor mesh):
- Implement CsiFrame, CsiMetadata, SubcarrierData types
- Implement Esp32CsiParser with binary frame parsing (magic/header/IQ pairs)
- Add parse_stream() with automatic resync on corruption
- Add ParseError enum with descriptive error variants
- 12 unit tests covering valid frames, corruption, multi-frame streams

All 275 workspace tests pass. No mocks, no stubs, no placeholders.
