Build the CFFI Python extension (_raylib_cffi.so) during wheel build instead of deferring to first import. This eliminates the need for libgl-dev and libx11-dev on the target system. - setup.py: run build.py after build.sh to compile CFFI extension - pyproject.toml: include _raylib_cffi*.so in package-data, bump to 5.5.0.3 - _shim_setup.py: extract .so files from wheel alongside data directory Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
