/**
 * design/80 — the file-backed `StorageBackend` for the local (TOC) single-user binary: the 3rd store impl
 * alongside `InMemory*` and `Pg*`, selected purely by what the embedder injects into `RunnerDeps` (no engine
 * change). Construct one over a single data root and pass its four members straight into `RunnerDeps`:
 *
 * ```ts
 * const backend = new FileStorageBackend(); // ~/.ai-agent (or $AGENT_DATA_DIR)
 * const runner = new Runner({
 *   brain,
 *   sessionStore: backend.sessionStore,
 *   checkpointStore: backend.checkpointStore,
 *   memoryStore: backend.memoryStore,
 *   toolResultStore: backend.toolResultStore,
 * });
 * // …on shutdown:
 * await backend.dispose();
 * ```
 *
 * **Single-instance-per-data-dir (§2.4 / §7 decision 4):** the constructor takes a coarse boot `flock` on
 * `root/LOCK`. A second `FileStorageBackend` over the same dir FAILS FAST ("another instance owns this data
 * dir"); a stale lock from a dead PID is pruned. The once-only checkpoint CAS is in-process (one event
 * loop), so there is still no per-operation lock. What this backend's lock does NOT cover — and never did,
 * despite what the store docs used to say — is a store constructed DIRECTLY off the root export (or one
 * this backend does not construct at all, like `FileWorkflowRunStore`); those now take their own
 * per-directory writer fence at construction ({@link import("./fs-atomic.js").acquireStoreDirLock}), so
 * the single-writer premise holds however the stores were assembled. Serving many writers CONCURRENTLY
 * (rather than refusing the second) is the Pg/TiDB backend's job, by design.
