Bulk delete merged staged batches by physically moving each loser's
files into the winner's batch dir with os.rename. Cross-volume bulks
(winner and loser on different filesystems) always hit EXDEV, forcing a
rollback and degrading to the batch_ids array with per-batch undo.
Merge is now manifest-only: loser entries are appended to the winner's
manifest with their staged paths unchanged, so staged files keep living
in each model's own .lm-pending-delete/<batch_id> dir (no data IO, no
EXDEV). Loser dirs are recorded in the winner manifest's merged_sources
and each loser manifest is stamped merged_into so its own purge timer, a
post-restart sweep or a direct undo call no-op. A cross-volume bulk is
one undoable batch again, and undo/purge clean up the loser dirs once
the merged batch settles.
- Remove delete_undo_enabled setting (backend default, frontend state,
settings modal UI, 10 locales); staged deletes with 30s undo are now
the only delete path and stale settings keys are silently ignored
- Remove the 1500ms delete-button arm delay (armDeleteButton) from all
delete modals; misclicks are recoverable via the undo toast
- Delete modal always shows the recoverable warning
- Log the first staged file path in staging log lines for easier support
