Update GUI/package-lock.json to upgrade rollup from 4.57.1 to 4.59.0. This updates the top-level rollup dev dependency and its many platform-specific optional packages (version, resolved URLs, and integrity hashes). Lockfile-only change from running npm install; no source code modifications.
Change the app title in GUI/index.html to "4 Gewinnt" to reflect the project name. Apply updates to GUI/src/Home.vue (UI/logic adjustments). Regenerate/normalize GUI/package-lock.json alongside these changes.
