Raylib alternatives: port one playable loop, not a screenshot

Raylib offers a lightweight programming approach to graphics and games. For Raylib alternatives, prototype the same tiny game loop in each candidate.

Prototype scope

• Open a window, handle input, draw sprites and text, play sound, and load assets.
• Measure frame timing on every target platform, not only the development machine.
• Check packaging, build size, language bindings, debugging, and documentation.
• Inspect ownership of the main loop and how much framework-specific code you must adopt.
• Confirm licensing and long-term maintenance for required dependencies.

Choose based on the team's programming model and deployment targets. An impressive editor may be unnecessary if you mainly need a small rendering library.
