Merge pull request '[GOFAI] Mega Integration — Accessibility + Debuff Fixes' (#76) from feat/beacon-mega-1775996281802 into main

Visual Identity Pass:
- Smooth phase transition overlay with staggered fade-in animation and particle burst
- Building purchase confetti at x10 milestones (gold + green particles)
- Animated resource counters (pulse on gain, shake on loss) - already existed, verified working

Ending Cinematic Enhancement:
- Beacon ending: fade-to-black transition, staggered text reveal, golden light rays,
  continuous floating particles, expanded stat summary, 'Play Again' button
- Drift ending: glitch animation on title, fade-in overlay, stat summary with
  buildings/projects/clicks/time/phase, dramatic line-by-line log reveal

Accessibility (#57):
- Sound mute toggle button (M key) with localStorage persistence
- High contrast mode toggle (C key) with CSS variable overrides
- Both toggles in fixed bottom-left toolbar with aria-labels
- Keyboard shortcuts M and C added, help overlay updated
- Drift ending button changed to 'Play AGAIN' with proper aria-label
