/**
 * The learn schedule (DES-learn-workflow §5): a durable record per learned topic saying how often
 * the daemon re-runs the `learn` workflow on it. Crew is the single source of truth for a
 * schedule; the topic's files in the repository do not repeat it.
 *
 * Same storage posture as `projects/settings.ts`: a small JSON map in the daemon's state home
 * (`learn-schedules.json`, following `--db`; `WICKED_CREW_LEARN_SCHEDULES` overrides), written
 * atomically (tmp + rename), read tolerantly per row (a malformed row is dropped, never the map).
