Trim OT-uninitialized prefixes from 3 .pt files (ep_005/012/017 — see `_contact_meta.trim_offset`); recompute bad_frames + data_quality_breakdown in trimmed coords; ot_loss frame count now reflects real mid-episode mocap dropout only. Recorder-side OT watchdog added to data_collection.py (in twm repo) so future episodes won't repeat the bug.
