What's Wrong?

When Claude Code makes edits to a file, the diff view in the console shows the file path as a clickable link and displays line numbers in the gutter. However, clicking the link navigates to the file but not to the
specific line where the change was made.

Use case:
When reviewing multiple edits across different parts of a file, it would be much faster to click directly to each change location rather than manually scrolling to find the modified lines.

Current behavior:

• Diff shows: Update(path/to/File.ts) (clickable)
• Line numbers shown in gutter: 22 +, 255 +, 660 +
• Clicking the link opens the file at line 1 if not already open, or just switches to the already open file at its current position

What Should Happen?

Expected behavior:

• Links should be formatted as file:line (e.g., path/to/File.ts:22)
• Clicking should navigate directly to the changed line in the IDE
