A prompt_archive table marks Library parents hidden from the shelf; older
builds ignore it. New routes /prompt_manager/library/delete/preview,
/library/delete and /library/restore classify a selection (delete,
archive, protected, already archived, not found), execute exactly what was
reviewed under a records hold, take a verified safety backup (disk checked)
before any delete, and restore archived prompts. The shelf, search and the
shelf-facing counts honor the archive (?shelf=active|archived); archiving
repairs a stale prompt hash so scans find the archived row.
