/**
 * WorkspaceStateStore backed by a directory tree.
 *
 * Each workspace is one self-contained directory (delete a workspace
 * by removing its folder):
 *
 * - `{root}/workspaces/{ws}/workspace.json` — metadata record
 * - `{root}/workspaces/{ws}/sessions/{sid}.json` — session table
 * - `{root}/workspaces/{ws}/namespace.json` — nodes + user, one JSON
 * - `{root}/workspaces/{ws}/history/<day>/<sid>.jsonl` — history
 *
 * The layout mirrors the S3 store file-for-object; mutable records get
 * the same generation-CAS contract via the lockfile protocol
 * (O_CREAT|O_EXCL mutex, tmp write, rename(2)), so multiple local
 * processes share one workspace with zero infrastructure: a CLI-created
 * workspace survives restart like `git init`. Local filesystems only;
 * anything cross-machine belongs on redis or s3. Mirrors the Python
 * DiskWorkspaceStateStore byte-for-byte on disk.
