Present now dispatches through a function pointer chosen at init and re-chosen by two new runtime setters: real vsync if requested and the driver grants it, else a manual sleep-based cap (auto-detects display refresh rate, falls back to 60fps if that can't be queried), else fully uncapped. skele_video_using_vsync() reports what was actually granted; skele_video_set_vsync()/skele_video_set_max_fps() let a game change either live without tearing down the renderer/GL context.
