/**
 * File Executor Registry (2.10.0).
 *
 * Local durable implementation of the ExecutorRegistryStore port. Records are
 * written atomically (unique temp + fsync + rename) and schema-validated on
 * load. Each executor record is independently locked cross-process with
 * proper-lockfile, so unrelated executor ids can mutate concurrently.
 *
 * Concurrency model mirrors FileDurableMissionStore: the lock protects only the
 * short read-validate-write critical section, never held across heartbeat
 * cadences, model inference, or resource collection.
