feat: add video generation core infrastructure and extend image generation parameters (#53681)

* feat: add video generation core infrastructure and extend image generation parameters

Add full video generation capability to OpenClaw core:

- New `video_generate` agent tool with support for prompt, duration, aspect ratio,
  resolution, seed, watermark, I2V (first/last frame), camerafixed, and draft mode
- New `VideoGenerationProvider` plugin SDK type and `registerVideoGenerationProvider` API
- New `src/video-generation/` module (types, runtime with fallback, provider registry)
- New `openclaw/plugin-sdk/video-generation` export for external plugins
- 200MB max file size for generated videos (vs default 5MB for images)

Extend image generation with additional parameters:
- `seed`, `watermark`, `guidanceScale`, `optimizePrompt`, `providerOptions`
- New `readBooleanParam()` helper in tool common utilities

Update plugin registry, contracts, and all test mocks to include
`videoGenerationProviders` and `videoGenerationProviderIds`.

Made-with: Cursor

* fix: validate aspect ratio against target provider when model override is set

* cleanup: remove redundant ?? undefined from video/image generate tools

* chore: regenerate plugin SDK API baseline after video generation additions
