Davids048andClaude Opus 5.5 f571621ae7 [refactor]: move examples to generate(request) and from_config
Every example calls VideoGenerator.generate with a nested request instead
of generate_video keywords, and passes settings outside the from_pretrained
convenience keywords through VideoGenerator.from_config at their typed
paths. Each request and generator config equals what the keyword call built.
