Scan panel rows whose range contains an exported clip's start time
are colored green. Priority: disabled > negative > exported > default.
Exported state refreshes automatically after an auto-export batch
completes on the current file.

When starting a scan export batch, delete old scan_export entries for
the same file+profile before writing new ones. Logs a warning when
replacing. Prevents stale entry buildup from repeated scan exports.

Two bugs caused vid number collisions (multiple files sharing a vid_NNN):
1. "First gap" assignment (n=1; while vid_n in existing: n++) would
reuse deleted vid numbers. Changed to max(existing) + 1 so numbers
always increase.
2. LIMIT 1 without ORDER BY returned arbitrary rows when a file had
entries in multiple vid folders. Added ORDER BY rowid DESC for
deterministic latest-wins behavior.

- Use microsecond-precision timestamps to prevent version merging on
sub-second scans

Add source_model column to hard_negatives table with migration. New
get_hard_negatives() returns full rows, delete_hard_negatives_by_ids()
for bulk deletion. get_training_data() gains use_hard_negatives param.
TrainDialog has "Use hard negatives" checkbox. Scan panel passes current
model name when marking negatives.

Add scan_timestamp column to scan_results. save_scan_results now inserts
with a timestamp and prunes versions beyond max_versions (default 5).
get_scan_results returns only the latest version by default, with optional
scan_timestamp parameter for loading specific versions. New get_scan_versions
method returns available versions for a (file, profile, model) tuple.

Ghost folders (scan-export-only) no longer appear in training dropdowns.
Also filters out 0-clip folders from get_training_stats.

- Fuse overlapping scan regions before display (merge adjacent 1s-hop windows)
- Hard negatives: mark false positives from scan panel for training feedback
- Toggle with "Add to Negatives" button, red text + red timeline regions
- Stored in dedicated hard_negatives table, always included in training

- Scan exports: saved to DB with scan_export flag, no timeline markers
- Training dialog checkbox to optionally include scan exports
- Single group folder per batch with area numbering (clip_042_a1_0.mp4)
- Export scan results: skip negatives, skip regions < 8s, respect spread
- Button shows estimated clip count, updates on spread/fuse/negative changes
- Timeline: reload scan regions on file load, "Clear all markers" context menu
- Default training model changed to HUBERT_XLARGE
