feat: camera-free 17-keypoint pose training (10 sensor signals)
Multi-modal pipeline using PIR, BME280, reed switch, vibration,
RSSI triangulation, subcarrier asymmetry — no camera needed.
Phases: multi-modal collection → weak label generation → enhanced
contrastive → 5-keypoint pose proxy → 17-keypoint interpolation
→ self-refinement (3 rounds) → LoRA + TurboQuant + EWC
Validated: 2,360 frames, 100% presence, 0 skeleton violations,
82.8 KB model (8 KB at 4-bit), 114.8s training
