Add environment variables for fine-grained control over TTS rate limiting and Better Auth behavior. Move documentation to external Docusaurus site with automated deployment workflows. - TTS rate limiting can now be enabled/disabled via TTS_ENABLE_RATE_LIMIT - Customizable daily limits for anonymous/authenticated users and IP backstops - Better Auth rate limiting can be disabled via DISABLE_AUTH_RATE_LIMIT - Rename library import env vars to IMPORT_LIBRARY_DIRS/DIR - Add docs-site with Docusaurus and GitHub Actions workflows - Update README to reference external documentation
