Assistant messages could not display inline images or attachments on the mobile client. The markdown renderer had no image block, and AssistantBubble only rendered MarkdownText + timestamp, ignoring message.attachments (only UserBubble did). - Add MdBlock.Image + standalone  parsing in MarkdownText. Accepts http(s) gateway URLs and data:image/...;base64 inline media. - Render message.attachments inside AssistantBubble (mirrors UserBubble) via InlineAttachment / AsyncImage. - Add parser unit tests for image blocks (url, data: URL, inline-in-paragraph). Local verification: ./gradlew ktlintCheck compileDebugKotlin assembleDebug all green; app-debug.apk produced. Fixes feature gap where agent-delivered media (e.g. MEDIA:/ images sent to chat) was invisible in the Android app. Co-authored-by: M57 <hy4ri@users.noreply.github.com>
