This change introduces Git stash support end-to-end, including a new backend command to list stashes and operations to push, apply, pop, and drop them. The frontend now fetches stashes as part of the repository bundle and provides a dedicated panel to manage shelved changes. - Add GitStash model and Tauri commands for stash operations - Implement StashPanel component and wire it into the app - Adjust sidebar layout and add stash-specific styling
