[Feature Request] Add button to open installation folder

Hi,
I would like to suggest adding a button to quickly open the game's version installation folder directly from the launcher(and maybe another one for the userdata).

Currently, it is difficult to find where the specific version is installed without checking the Task Manager while the game is running. Having a shortcut in the UI would be very helpful for managing files manually.

The launcher is built with Tauri (Rust backend) and React frontend. Look for the UI component that displays game versions and the Rust code that manages file paths and OS-specific folder opening. Check how the current installation directory is determined and add a button that triggers a system command to open that folder. Test on the target OS (Windows/Linux/macOS) to ensure the open command works correctly.
