SeekQuote Web v0.1.10

- Video export now uses the same canvas.captureStream(30) + MediaRecorder path
  as the working SeekQuote plugin.
- Removed the iPhone-only manual requestFrame capture logic.
- Removed forced keyframe options.
- Removed the added silent-audio injection so the recorder matches the plugin.
- Runs in Kent branding now has a stable cross-version browser backup and
  auto-loads again after web app updates.
- Script history, current script draft and recent script hooks now use the same
  stable cross-version backup, so updating SeekQuote Web does not wipe them.
