 * cleanup-drafts.php — Delete orphaned draft theses older than 24h.
 *
 * Draft theses are created with status='draft' during the two-phase commit
 * in ThesisCreateController. If the file phase throws after COMMIT, the
 * draft remains orphaned — no files attached, but blocks the identifier.
 *
 * Usage:
 *   php scripts/cleanup-drafts.php              # dry-run (list candidates)
 *   php scripts/cleanup-drafts.php --no-dry-run # actually delete
 *
 * Exit codes: 0 on success, 1 on error.
