Claude 2199174cac feat: Add commodity sensing, proof bundle, Three.js viz, mock isolation ...

Commodity Sensing Module (ADR-013):
- sensing/rssi_collector.py: Real Linux WiFi RSSI collection from
  /proc/net/wireless and iw commands, with SimulatedCollector for testing
- sensing/feature_extractor.py: FFT-based spectral analysis, CUSUM
  change-point detection, breathing/motion band power extraction
- sensing/classifier.py: Rule-based presence/motion classification
  with confidence scoring and multi-receiver agreement
- sensing/backend.py: Common SensingBackend protocol with honest
  capability reporting (PRESENCE + MOTION only for commodity)

Proof of Reality Bundle (ADR-011):
- data/proof/generate_reference_signal.py: Deterministic synthetic CSI
  with known breathing (0.3 Hz) and walking (1.2 Hz) signals
- data/proof/sample_csi_data.json: Generated reference signal
- data/proof/verify.py: One-command pipeline verification with SHA-256
- data/proof/expected_features.sha256: Expected output hash

Three.js Visualization:
- ui/components/scene.js: 3D scene setup with OrbitControls

Mock Isolation:
- testing/mock_pose_generator.py: Mock pose generation moved out of
  production pose_service.py
- services/pose_service.py: Cleaned mock paths
