Add window state persistence

- Add `tauri-plugin-window-state` to remember window position and size across launches
- Create `desktop.json` capability with `window-state:default` permission
- Set `visible: false` in `tauri.conf.json` to prevent flashing on restore (plugin shows window after restoring state)
- State stored in ``~/Library/Application Support/com.veszelovszki.rusty-commander/.window-state.json`
