Update project documentation and configuration for 2D gameplay. Changed rendering method to Mobile in project settings, clarified main scene structure in CLAUDE.md, and detailed autoload components in ARCHITECTURE.md. Adjusted README.md to reflect the new main scene and removed references to Forward+ rendering.
