Subject: [PATCH] Fix classical playability: louder orchestra, no stacked notes

Three fixes for classical mode:

1. Louder background orchestra: bg volume boosted 1.5x in
   beginClassical so the full orchestra is clearly audible
   during gameplay, not drowned out by hit sounds

2. No more impossible stacked notes: buildClassicalNotes now
   enforces a 0.12s minimum gap between consecutive hittable
   notes. This removes physically impossible simultaneous hits
   while keeping 94-100% of notes in most pieces. Flight of the
   Bumblebee goes from 206 to 140 notes (still 4 notes/sec).

3. Balanced hit volumes: drum hits during classical mode reduced
   from gain 8 to gain 3 so they don't overpower the orchestra.
   Orchestra hit sounds boosted (strings 0.7, brass 0.4). Miss
   feedback reduced to gain 2.
