videobook 0.2.3

Added

• Fal FLUX 3 Max text-to-video, image-to-video, and keyframes-to-video,
  with generated audio and resolution-tiered per-second cost estimates.
• Bria Fibo 2 text-to-image with structured VGL prompts, and Fibo 2 Edit
  for one to four reference images, including the image editor.
• H3 Max Reframe Video, which outpaints a source video to a target aspect
  ratio at 480p, 768p, or 1080p while keeping its audio and timing.
  Priced from fal's historical average because the request does not fix
  the billed duration.

Changed

• Upgrade all application @apicity/* dependencies to 0.16.3.
• Windows x64 is supported. The release check runs the pack-and-install
  smoke on Windows and blocks the release when it fails. Stopping
  videobook serve from another process still ends it without a clean
  shutdown, because Windows has no SIGTERM, and the next start replaces
  the lock file.
• Dynamic fal requests are priced from fal's historical average when
  FAL_ADMIN_API_KEY is set. Without the key, and for the two Seedance
  formula gaps, the estimate stays at the local $0.
