Admin maintenance workbench for doing many changes safely. Multi-select posts and apply status, board, tag, post type, archive/delete, lock/unlock, merge duplicates, assign estimated release date, or export selected rows. Shows a confirmation preview of exactly what will change before applying.

Implementation: selection mode in feedback list/kanban, server action with per-row authorization, background job for large operations, audit_events for every bulk mutation, and undo support where feasible. This prevents admin work from becoming 50 individual clicks.
