- township: new playback_fps (0 = same as generation fps). coderai uses fps only
  for the mp4 encode (Wan generates a fixed frame count), so a higher playback
  fps plays the same frames faster (less slow-motion). The planner counts clip
  duration as nf/playback_fps so the finals reach their target length at the real
  play speed. Wired through config/CLI (--playback-fps)/web form/all call sites.
- main.py: suppress /v1/{video,images,audio}/progress access-log lines unless
  --debug-web is set (matching the existing /v1/loras/progress filter).
