feat: --narrate opt-in narration, panel variety mandate, v0.23.0v0.23.0

- Add --narrate flag (default false); narration is now opt-in to save TTS quota
- Add VARIETY MANDATE to story page prompts: each panel must differ in camera
  angle, pose, location, lighting, and foreground — prevents repeated compositions
- Wire NarrateEnabled through RunnerConfig and main.go
- Update README: --narrate flag, updated output file table, narrator voice examples
