[FEATURE]:Pasted images use data: URL instead of file path, breaking MCP tools for non-vision models #14673

Describe the enhancement you want to request
Problem
When pasting an image from clipboard, OpenCode stores it as a data: URL (base64).
This works for vision models (GLM-4.6V), but non-vision models (GLM-5) need to
call MCP tools (look_at, understand_image) which expect file paths, not data URLs.
Expected Behavior
Pasted images should be saved to a temp file, and the url field should contain
the file path so MCP tools can access them.
Workaround
Use @filename to reference files already in the working directory.
