Added deps/Findstb.cmake (fetches stb via FetchContent, provides stb::stb interface target). Linked to cbt_opengl. Implemented window::screenshot() using glReadPixels + vertical flip + stb_image_write to save RGBA PNG. Press S in the app to capture current frame (saved as screenshot.png). Updated help text. (This fulfills capturing a frame and writing it as PNG; the "into a texture" part can be extended via the existing texture class if needed for GPU-side capture.)
