feat: Feature 2.2 — Line Movement + Cascade Detection
Line movement system: - Baseline capture on first odds fetch of the day - Movement detection >= 0.5 points with direction (up/down) - Sharp money heuristic (sharp_action/public_action/unknown) - GET /api/movements with player, stat_type, min_movement filters - Movements included in GET /api/odds/nba live responses Cascade detection system: - Scratch detection: player props disappear from 2+ books - Affected user lookup via scan_sessions + picks - Parlay re-grade without scratched legs - cascade_alerts created for affected users - GET /api/alerts (Analyst/Desk only), PATCH /api/alerts/:id/read Zero extra Odds API credits — all detection piggybacks on existing fetches. Migration 002: line_baselines, line_movements, cascade_alerts tables. 30 new tests, 188 total (161 Node.js + 27 Python), all passing. Phase 2 Core Product COMPLETE.
