Re-export button (next to Spread spinner) re-exports all manual clips
for the current file into the current folder with the new spread value.
Old files are deleted from their original locations first.
Duplicate profile option in the profile dropdown copies scan_results,
hard_negatives, and hidden_files to a new profile name (exports are not
copied since they reference file paths tied to the source profile).
Also widened get_profiles() to include profiles that only have
scan_results or hard_negatives, not just exports.

Add "Merge N rows" context-menu option that combines selected scan rows
into one (min start, max end, max score), with full undo support.
Ctrl+Z is now an application-wide shortcut so it works regardless of
which widget has focus. Negatives undo now respects the exported-green
row color instead of reverting to default.

- Right-click on exported (green) rows shows "Delete export" to wipe
associated clip files, annotations, DB rows and empty vid folders;
scan panel, markers and playlist badge refresh afterwards.
- Exporting with rows selected in the scan panel now runs a partial
export: prior scan exports are preserved, and the area index for new
clip filenames is offset past existing a-suffixes in the vid folder
to avoid collisions.

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.

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.
