Three defects in how the mirror tracked its source, all of which show up on a library that something else reorganises. Pruning probed the source tree for a mirror file's original name, trying each known extension in turn. A source saved as .FLAC was never found, so its mirror file was deleted as an orphan and re-encoded on the next pass, for ever. Pruning now works from the set of paths the pass actually accounted for, which cannot disagree with the walk over letter case or extension coverage. Two sources could also claim one mirror path -- 01 Song.flac beside a leftover 01 Song.mp3, which is what an interrupted upgrade leaves behind. Both encoded to the same destination, whichever finished last won the race, and every later pass found the other one stale. The best-quality source now wins, ties break on path, and the loser is logged. The source mtime was read after encoding rather than before. A file still being written when the pass reached it would be stamped with its final mtime while holding truncated audio, and would never be revisited. Adds regression tests for all three, plus the format-upgrade, album-rename and whole-library-deletion cases, each verified to fail before the change.
