v0.1.1

Fixed

• Vision / image attachments in Copilot. Read input_attachment_types and max_input_attachments from the DIAL deployment listing. Models with any allowed image/* MIME now expose capabilities.imageInput in the VS Code model picker (previously only url_attachments_supported / folder_attachments_supported were considered, so most vision models looked unsupported).
• Forward inline images to DIAL. Copilot LanguageModelDataPart image bytes are encoded as custom_content.attachments[].data (base64) on the chat completion request, with MIME allow-list enforcement and optional max_input_attachments cap.
• input_attachment_types wildcards. DIAL patterns such as */*, audio/*, and image/* are matched against Copilot attachment MIME types (in addition to exact types like image/png).
• Ignore Copilot cache_control data parts. Prompt-cache markers (mimeType: cache_control, data: ephemeral) are Copilot protocol metadata, not DIAL attachments; they are skipped instead of being sent as custom_content.attachments.
