M4 handover: coordinate fixes, detector registry, deploy v2, YOLOv8s, identity lifecycle

- Fix swift_pose/swift_ocr Y-flip bugs (BUG-003~006)
- Add heuristic_scene module + post-processing trigger (replaces Places365)
- YOLOv5nu → YOLOv8s CoreML (+33% detections, +390% scene indicators)
- Per-table SQL export (split 4.7GB single file → 478MB max per table)
- Version/build check in deploy.sh (compare /health vs file_info.json)
- Add file_uuid column to identities table + backfill
- Identity pre-clean step in deploy (avoids UNIQUE conflicts on re-deploy)
- Stranger_xxx naming fix with UUID context
- Add DETECTOR_REGISTRY.md (25 detectors), DETECTOR_SELECTION_SOP.md
- Update SPATIAL_COORDINATE_REGISTRY.md (P layer, 6-layer architecture)
- New IDENTITY_LIFECYCLE.md
- M4 response docs for deploy_script_fix and 111614 test report
