Problem Statement

Currently when Claude proposes an edit via the Edit tool, the diff is shown inline in the chat.

Proposed Solution

It would be helpful if the proposed change appeared in the IDE's Git panel (as "pending changes") so users can review the diff using the IDE's familiar diff view before accepting or rejecting the edit.

Additional Context
