* feat(server): cross-node RSSI-weighted feature fusion + benchmarks Adds fuse_multi_node_features() that combines CSI features across all active ESP32 nodes using RSSI-based weighting (closer node = higher weight). Benchmark results (2 ESP32 nodes, 30s, ~1500 frames): Metric | Baseline | Fusion | Improvement ---------------------|----------|---------|------------ Variance mean | 109.4 | 77.6 | -29% noise Variance std | 154.1 | 105.4 | -32% stability Confidence | 0.643 | 0.686 | +7% Keypoint spread std | 4.5 | 1.3 | -72% jitter Presence ratio | 93.4% | 94.6% | +1.3pp Person count still fluctuates near threshold — tracked as known issue. Verified on real hardware: COM6 (node 1) + COM9 (node 2) on ruv.net. Co-Authored-By: claude-flow <ruv@ruv.net> * fix(ui): add client-side lerp smoothing to pose renderer Keypoints now interpolate between frames (alpha=0.25) instead of jumping directly to new positions. This eliminates visual jitter that persists even with server-side EMA smoothing, because the renderer was drawing every WebSocket frame at full rate. Applied to skeleton, keypoints, and dense body rendering paths.
