feat(signal): implement Phase 5 Reliability & Intelligence
Phase 5 deliverables: - Diurnal adaptive baseline (24-slot hourly vectors, 7-day learning, crossfade, confidence indicator) - Stationary person detection (breathing band 0.1-0.5 Hz, long-dwell logic with health gating) - Ambient confidence score (per-link health: SNR, phase stability, packet rate, drift; composite gauge) - Link weather diagnostics (root-cause suggestions, weekly trends, repositioning advice) - Baseline persistence (SQLite storage for EMA and diurnal baselines) Key components: - signal/diurnal.go: 24-hour baseline slots with cosine crossfade - signal/breathing.go: 4th-order Butterworth bandpass filter for breathing detection - signal/ambient.go: Per-link health scoring with weighted composite - signal/persist.go: SQLite persistence for baselines - signal/healthpersist.go: Health log aggregation for weekly trends - diagnostics/linkweather.go: 5 diagnostic rules with actionable advice - diagnostics/reposition.go: GDOP-based repositioning target computation - fleet/healer.go: Self-healing fleet with role re-optimization - dashboard/js/app.js: Quality gauge UI with health polling Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
