 * Cache clear tool — no-op after xattr metadata cache removal.
 *
 * The per-file xattr metadata cache (user.gas.updateTime, user.gas.fileType,
 * user.gas.contentHash) has been replaced by the local git repo as the
 * content cache. This tool is retained to avoid breaking existing callers
 * but performs no operation.
 *
 * To force a fresh remote fetch, use: cat({..., preferLocal: false})
 * To pull all files from remote, use: rsync({operation: 'pull', scriptId})
