Beethoven's 5th: full continuous orchestra, 88s to natural break

Complete rewrite with new architecture:
- CONTINUOUS HARMONIC BED: sustained string/woodwind/bass chords
  playing throughout all 88 seconds, changing with the harmony
  progression (Cm→Ab→Gm→Cm→G→Cm). Not hittable — just ambiance.
- Running 8th-note string passages between melody sections
  (background texture filling the spaces)
- 877 background nodes (was 565) creating a full orchestral sound
- 102 hittable melody notes (was 113) — only the STRONG accents
  (motif hits, chord downbeats, scalar peaks)
- Duration extended from 54s to 88s (~1:27) ending at the natural
  break where the exposition concludes before development

The player is now one voice IN the orchestra, hitting the famous
da-da-da-DUM moments while the full ensemble plays around them.
