v0.5.0 public 3

v0.5.0 — Turn-navigator music wave The official turn navigator's marks now dance with the audio DSH itself plays: page media elements are analyzed in place (kept audible) and drive a beat-synced travelling wave plus per-tick band jumps, Wallpaper-Engine-visualizer style. Total silence = every tick at rest. Merged from the retired dsh-plugin-pulse-divider.
