VS Code extension diff opening feels slower than native VS Code diff

What issue are you seeing?
Opening diffs from the Codex VS Code extension feels significantly slower than opening the same file diffs through VS Code's native diff editor.
For quick change inspection, the current Codex diff/review UI path feels heavier than necessary. It appears to route through the Codex panel/review experience instead of opening the file comparison directly in VS Code's native diff editor.
What steps can reproduce the bug?
- Use the Codex VS Code extension to make or review a local code change.
- Open a changed file's diff from the Codex panel.
- Compare the perceived latency with opening the same changed file through VS Code's native Source Control diff.
What is the expected behavior?
Diffs opened from the Codex extension should be as fast as VS Code's native diff editor for quick file inspection.
It would help if Codex either opened file diffs through VS Code's native diff editor directly, or provided a setting such as "Open diffs in native VS Code editor".
