Fixed
- Detection no longer silently fails on .m4v (and other taggable files whose in-place write fails). It detected the language but, because .m4v isn't "untaggable", reverted to und with no hint when the ipod-muxer remux failed. Now any failed write keeps the detected language as pending — showing the "detected → convert to MKV to apply" hint and offering it in the post-detect remux dialog.
