Patch Changes 4d1b345: feat(provider/moonshotai): own the chat implementation, support video input. The provider no longer builds on `@ai-sdk/openai-compatible`; the converter, language model, and helpers are owned by the package. Video file parts (e.g. `mediaType: 'video/mp4'`) are converted to Moonshot's `video_url` content parts for video-capable models (`kimi-k3`, `kimi-k2.7-code`, `kimi-k2.6`, `kimi-k2.5`). Audio and PDF file parts now throw client-side (the API rejects those part types). `reasoningHistory: 'preserved'` now maps to Moonshot's `thinking.keep: 'all'` request field (previously a no-op, the API ignores `reasoning_history`), gated per model with a warning on models without `thinking.keep` support.

Adds `promptCacheKey` and `safetyIdentifier` provider options, widens `reasoningEffort` to `'low' | 'high' | 'max'` per Moonshot's docs, maps the generic `reasoning` call option to `reasoning_effort`, and passes `ms://` Files API references through natively (declared in `supportedUrls`).
