/**
 * File Scheduler Store (2.12.0).
 *
 * Local durable implementation of the SchedulingIntentStore port. One small
 * record file per intent, schema-validated on load, written atomically
 * (unique temp + fsync + rename). Intent identity is deterministic per mission
 * (`intent_<missionId>`), so enqueue and tick are idempotent across processes.
 *
 * Cross-process model:
 *   - All mutations for an intent serialize on a per-intent proper-lockfile
 *     lock. Two processes racing to enqueue/transition the same mission's
 *     intent therefore serialize; the loser observes the winner's record.
 *   - Unrelated intents lock different paths and never globally serialize.
