Feature request: Add intraline diff highlighting to Codex review.

Current behavior: Codex shows changed lines in the diff, but when a long prose line is edited, the whole line appears changed. If only one word, number, or phrase was modified, it is hard to identify the exact edit.

Requested behavior: Keep the normal line-level diff view, but also highlight the changed words, numbers, or phrases inside each changed line. This should work like intraline diff highlighting in GitHub, VS Code, or other code review tools.

Generic example: Original: The system achieved a score of 0.80 in the final test. New: The system achieved a score of 0.85 in the final test.

The diff should show the full line for context, but highlight only 0.80 as removed and 0.85 as added.

This is especially useful for LaTeX, Markdown, documentation, and other prose-heavy files where paragraphs are often stored as long lines.
