feat(audio): MP3 asset support in tracker via decode-at-init
Detect MP3 blobs by magic bytes in tracker_init(), decode to spectrogram
(hamming window + FDCT) using new mp3_decode(), and register with synth
exactly like .spec assets. STRIP_ALL builds guard with FATAL_CHECK.
handoff(Gemini): MP3 assets now usable in music.track with SAMPLE ASSET_*
syntax; see doc/TRACKER.md for usage. No synth/compiler/packer changes.
