[Bug] Unsupported SVG media type in conversation history with Figma MCP assets

Bug Description
SVG is the issue!

The Figma assets are SVG files, which the Claude API doesn't support in conversation history.

Complete Issue Breakdown:

What happened in my last session:

1. Figma MCP returned asset URLs → https://www.figma.com/api/mcp/asset/...
2. Downloaded SVG content from these URLs
3. Tried to embed SVG as image in conversation → API ERROR (unsupported media_type)
4. Conversation corrupted, can't continue or compact

causes error:
Figma URL → Download SVG → Embed in conversation → ERROR
