- Add SetStagedFileOps to Extension: sets fileOps without enabling DirectFileMode, so WASM clients use staged retrieval (WaitingFiles, OpenFile, DeleteFile) instead of direct-write mode. - Add directFileOps bool field: SetFileOps (Android SAF) sets it true; SetStagedFileOps (WASM JS) leaves it false. onChangeProfile now uses `fops != nil && e.directFileOps` to determine DirectFileMode. - Add jsCallVoid to jsFileOps: void ops (openWriter, write, closeWriter, remove) now use cb(err?: string) instead of cb(null, err: string). - Fix waitingFiles() returning JSON null when no files are waiting: normalise nil slice to empty slice before marshalling. - Update wireTaildropFileOps to call SetStagedFileOps.
