+Add image support for VS Code LM API provider
+
+- Upgraded @types/vscode to ^1.106.0 to support LanguageModelDataPart
+- Modified vscode-lm-format to convert image blocks to LanguageModelDataPart.image()
+- Updated VsCodeLmHandler.getModel() to detect image-capable models based on model family
+- Updated useSelectedModel to use model's supportsImages capability instead of always false
+- Added tests for image conversion functionality
+
+This enables users of the VS Code LM API provider to upload images when using vision-capable models like GPT-4o, Claude 3.5 Sonnet, and Gemini models through GitHub Copilot.
