fix: Fix macOS CI cairo library loading

The macOS GitHub Actions runners weren't finding the cairo library even
after installation. This fix adds proper environment variables:
- PKG_CONFIG_PATH for pkg-config to find cairo
- DYLD_LIBRARY_PATH for runtime library loading

This should resolve the import errors on macOS CI runs.
