v0.5.9 - Steam Cloud

This update enables Steam Cloud saves on all platforms: Windows, macOS, Linux, and Steam Deck. Please report any issues you encounter.

• Only save files are synced, not game settings. This allows you to maintain different configurations on Steam Deck and other platforms.
  
• macOS: Previously, save files were stored inside the app bundle. They are now located in the same folder where the game is installed. Existing saves will be moved to the new directory the next time the game is run.
