Accusys 6851cb4734 feat: add identity_matcher.py for multi-angle face matching ...

Implements:
- match_faces_round_1: TMDb seeds → traces (TH=0.55)
- match_faces_round_2: Confirmed traces → pending (TH=0.55)
- match_faces_round_3_plus: Propagation (TH=0.50)
- cluster_strangers: Greedy merge unmatched traces (TH=0.40)
- multi_angle_match: max(cosine(seed, rep)) across 3 representatives
- cosine_similarity: Vector similarity calculation

Usage:
  python identity_matcher.py --file-uuid <uuid> --round 1
  python identity_matcher.py --file-uuid <uuid> --round 2 --confirmed-traces 1,2,3
  python identity_matcher.py --file-uuid <uuid> --round 1 --stranger

Output: JSON with suggestions {trace_id: {identity_id, uuid, name, score, suggested_by}}
