The "gui_2d_vis" directory has been renamed to "pygame_2d_vis". All references to "gui_2d_vis" in imports and file paths throughout the code have been updated to the new name. The renaming is clearer about the visualization library used and aligns with project conventions for directory naming.

All instances of 'overcooked_simulator' have been replaced with 'cooperative_cuisine'. This includes changes in file paths, imports, and script names. The necessary adjustments to reflect this rename have also been made in the documentation, setup files, test scripts, and CI/CD configuration.
