 * Classification per dir:
 * - `origin.json` present and its recorded path still exists → keep the dir,
 *   but flag a leftover `lancedb/` subdir (dead since the SQLite engine swap).
 * - `origin.json` present, recorded path gone → orphaned → prune.
 * - no `origin.json` (pre-2.3.1 dirs can't prove their origin) → prune only
 *   when untouched for {@link UNKNOWN_DIR_MAX_AGE_MS} — or immediately with
 *   `--aggressive`, which treats unprovable dirs as junk (safe: every live
 *   project rewrites origin.json on its next memory access).

 * Exported for tests. Never returns `progress.md` (the taskdev recovery ledger),
 * directories, or loop JSON it cannot parse — deleting the unclassifiable loses data.
 *
 * A loop JSON is only ever classified as abandoned when it has a real, positive,
 * numeric `nextRunAt` timestamp that is more than a day in the past. Live producers
 * write `nextRunAt: 0` (real /do loops) or `nextRunAt: null` (dashboard) — those,
 * along with missing/non-numeric values, are never eligible for deletion regardless
 * of `status`, since a crashed daemon can leave a stale `status: 'running'` behind.
