/**
 * Access the file system.
 *
 * ## Security
 *
 * This module prevents path traversal, not allowing parent directory accessors to be used
 * (i.e. "/usr/path/to/../file" or "../path/to/file" paths are not allowed).
 * Paths accessed with this API must be either relative to one of the {@link BaseDirectory | base directories}
 * or created with the {@link https://v2.tauri.app/reference/javascript/api/namespacepath/ | path API}.
 *
 * The API has a scope configuration that forces you to restrict the paths that can be accessed using glob patterns.
 *
 * The scope configuration is an array of glob patterns describing file/directory paths that are allowed.
 * For instance, this scope configuration allows **all** enabled `fs` APIs to (only) access files in the
 * *databases* directory of the {@link https://v2.tauri.app/reference/javascript/api/namespacepath/#appdatadir | `$APPDATA` directory}:
 * ```json
 * {
 *   "permissions": [
 *     {
 *       "identifier": "fs:scope",
 *       "allow": [{ "path": "$APPDATA/databases/*" }]
 *     }
 *   ]
 * }
 * ```
 *
 * Scopes can also be applied to specific `fs` APIs by using the API's identifier instead of `fs:scope`:
 * ```json
 * {
 *   "permissions": [
 *     {
 *       "identifier": "fs:allow-exists",
 *       "allow": [{ "path": "$APPDATA/databases/*" }]
 *     }
 *   ]
 * }
 * ```
 *
 * Notice the use of the `$APPDATA` variable. The value is injected at runtime, resolving to the {@link https://v2.tauri.app/reference/javascript/api/namespacepath/#appdatadir | app data directory}.
 *
 * The available variables are:
 * {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#appconfigdir | $APPCONFIG},
 * {@linkcode https://v2.tauri.app/reference/javascript/api/namespacepath/#appdatadir | $APPDATA},
