Add delay/reverb dry-wet, granular randomize toggles, rework accent DSP

- Add delay and reverb Dry/Wet parameters and knobs, wired into presets
- Add Accent/Slide/Fine/Rate toggles to the Randomize panel with new
  per-aspect pattern randomizers
- Soften accent: modest volume lift plus small cutoff and filter-attack
  modulation instead of the heavy 5x gain boost
- Halve reverb comb/allpass delays so the wet speaks sooner
- Regenerate a fresh build stamp on every build
