What changed

• Forward image blocks from Codex ACP's MCP tool results through Codeg's existing image preview field.
• Read inline images from the original Codex function output when restoring history. The persisted tool event can contain a truncated text preview instead of the image.

Validation

• Installed the patched macOS app locally and opened its Web Service. A real Computer Use screenshot of Calculator appeared in both clients.
• Refreshed Web and reopened the execution group. The screenshot was still available.
• Imported the Chrome/Baidu conversation that reproduced [Bug] Missing screenshot previews for Codex Computer Use MCP results #1129 and opened the original screenshot in both desktop and Web.
• Passed the Rust regression tests for live tool updates and history, the macOS build, the Web build, and preview tests.
