Rewrite Ride of the Valkyries in conductor-style
Replaced 5-line tp() call with full conductor-style arrangement: - Continuous Bb major harmonic bed across 8 sections - tutti() helper for full orchestral hits - gallop() helper for the iconic 9/8 compound rhythm - 8 sections: intro tremolo → first horn call (p) → second statement (f) → Eb major development → fff recapitulation → climax → power chords → coda - Famous ascending Bb-D-F arpeggio as hittable melody - Running string arpeggios as background texture - Duration expanded from ~35s to ~88s https://claude.ai/code/session_01TFVkxq4PYhkSFGYHEi4uqY
