perf(tkg): eliminate N+1 Qdrant HTTP requests in TKG builders

Browse Source

- Add build_frame_index() for O(1) frame-to-face lookup
- Add find_trace_in_frame() for in-memory bbox matching
- Share face_points across all 6 TKG builders (was 4x redundant fetches)
- Remove get_trace_for_face() (31,666 HTTP requests → 0)
- Change Qdrant scroll error from warn to error
- build_lip_track_nodes_from_pg: uses frame_index instead of per-face HTTP
- build_appearance_trace_nodes: uses frame_index instead of per-face HTTP
- Expected speedup: ~200-600x for lip_track build on large files
