This change introduces new Tauri commands to amend the last commit with an optional message, fetch the last commit message, and undo the most recent commit safely. The UI now offers an amend toggle and an undo button only when the last commit hasn’t been pushed upstream, reducing the risk of rewriting shared history. - Add amend/undo/last-message git commands in Rust - Wire new operations into the Svelte commit panel UI - Add styling and state handling for amend mode
