Inline diff review in Claude Code GUI before file writes

Problem Statement

When Claude Code makes file edits via the GUI on the Desktop app (non-CLI), there is no way to review the diff before it is written to disk. In the CLI, edits are shown as diffs with a prompt to approve or deny each change.

It would be great to have the same inline diff review experience in the GUI — showing the before/after of each file change with an approve/reject action before the write is committed to disk.

Current behavior: File edits are written to disk immediately upon Claude's action; changes only visible after the fact in an external editor.

Proposed Solution

Expected behavior: A diff view is shown in the GUI for each file edit, allowing the user to approve or reject before the change is written.
