/**
 * THE DISK LEAK. This is the headline defect spec 052 exists to close.
 *
 * `uploads/templately/tmp/{session_id}/` holds an extracted template pack —
 * routinely 100–500 MB of XML, JSON and media. Before this task, nothing ever
 * removed one unless an import FINISHED, and even then only on a 1-in-20
 * random chance. An import that failed or was abandoned left its pack on disk
 * permanently, and the scheduled cleanup made it worse by deleting the session
 * record, so nothing referenced the directory any more.
 *
 * A directory is reclaimable when it is EITHER orphaned (no session record at
 * all — the common case after the old record-only cleanup ran) OR its session
 * has passed the retention window. An active import is never touched, and that
 * is re-checked immediately before each removal rather than when the candidate
 * list was built.
