Subject: [PATCH] fix(ffi): pass transparent=false to all surface_create_*
 calls

All platform variants of surface_create (Windows, Wayland, X11, Linux
auto-detect) gained a `transparent: bool` parameter in processing_render
but the FFI wrappers were not updated to match, causing a compile error.
macOS was already correct. Pass `false` (opaque) to match existing behaviour.
