Subject: [PATCH] fix: keep separators when removing their anchor file; add
 Copy name

- _remove_paths re-anchors a separator to the next surviving file (or a
  trailing separator) instead of dropping it when its anchor is removed;
  used by both Remove and Delete-from-disk. Removal now persists tabs.
- Add "Copy name" / "Copy N names" to the playlist context menu (basenames
  to clipboard, newline-joined for multi-select).
