Module cotis 

Cotis context trait implementations for crate::renderer::RaylibRender.

Bridges Cotis’s window/frame/render context traits and text measurement to raylib:

• CotisWindowContext (cotis_utils::traits) — screen dimensions from raylib.
• CotisFrameContext — frame delta time.
• CotisRenderContext — provided automatically via blanket impl when window and frame contexts are implemented.
• RendererTextMeasuringProvider — layout text sizing via crate::functions_raylib::raylib_measure_text_inner.
