docs: ADR-081 gesture-controlled data visualization
Camera + CSI fusion for hands-free chart manipulation:
- 11 arm-level gestures (CSI-detectable): swipe, circle, hold, spread
- 7 finger-level gestures (camera-required): pinch, point, grab, thumbs
- Fusion engine: camera precision + CSI through-wall capability
- Chart types: line, bar, 3D scatter, heatmap, gauge, spectrogram
- Visual feedback: gesture cursor overlay + state indicator
- WebSocket protocol for gesture events → UI commands
- Dual-mode: fusion (full precision) or CSI-only (works in dark)
- Builds on WiFlow (ADR-079) + DTW gestures (ADR-029)
