Save History, Load Browser & Gameplay Polish Update — Omnicore: Freiza's Retribution Steam update #397963

This update focuses on making saves safer, easier to manage, and clearer to use, while also polishing several gameplay systems across the wider game. Highlights: - Added a save browser for loading saved games from the main menu and in-game menus. - Added save history support, so manual saves and autosaves can exist as separate snapshots. - Added support for named saves and renaming saves. - Improved the load-game list so the editable save name is highlighted in a different color, making it easier to recognize. - Improved save loading so the game can route back to the correct area more reliably. - Added snapshot tests for the save system. - Improved autosave behavior across travel, expedition, auction, and result flows. - Polished galaxy, battle, transfer, and menu UI behavior. - Cleaned up development files and removed outdated guide text from the project. Thank you for playing and suppo...
