fix(node): skip indexing audio files under 50KB, likely-corrupt source

The "P.H. Theme" failure investigated earlier turned out to be a genuinely
corrupt 1256-byte source file with no audio stream at all, just an ID3
tag — a real, if rare, corruption pattern worth guarding against directly
rather than only handling gracefully at playback time. Scoped to audio
only, applied wherever a file actually gets hashed/typed (fresh scan and
the cache-miss rehash path alike) — a tiny file of any other type is still
indexed normally.
