Subject: [PATCH 2/3] fix: handle non-text data URLs to prevent Windows
 clipboard paste crash When pasting images from clipboard on Windows 11, the
 app crashed with: TypeError: The URL must be of scheme file
 (ERR_INVALID_URL_SCHEME) Root cause: The data: case only handled text/plain
 and broke, causing non-text data URLs to fall through to file: case which
 called fileURLToPath() on a data: URL. Fix: - Return non-text data URLs
 directly instead of breaking - Add default case to prevent fall-through for
 unknown protocols
