This commit resolves a bug where the `write-file` operation could fail to render content due to a missing filename.
The fix involves:
- Ensuring `fileName` is consistently passed to `DiffRenderer.tsx` through `ToolConfirmationMessage.tsx`, `ToolMessage.tsx`, and `useGeminiStream.ts`.
- Modifying `edit.ts` and `write-file.ts` to include `fileName` in the `FileDiff` object.
- Expanding the `FileDiff` interface in `tools.ts` to include `fileName`.
Additionally, this commit enhances the diff rendering by:
- Adding syntax highlighting based on file extension in `DiffRenderer.tsx`.
- Adding more language mappings to `getLanguageFromExtension` in `DiffRenderer.tsx`.
- Added lots of tests for all the above.

- Did not update details that impact GC execution. Meaning packages are still named gemini-code (for now) and things that import them still import them as gemini-code.
- Motivation of this upgrade is to enable us to get convenient access to the thinking budget config changes for 2.5 thinking models. This will be key to getting our model to take a bit more time for various requests.
