The 3.3.0 patch (patches/cython/3.3.0/) does not apply to 3.2.9: its aarch64 override context includes an inherit.environment = "append" line that 3.2.9's pyproject.toml does not have. Add a version-specific patch carrying the same riscv64 CFLAGS override, matching 3.2.9's own override style.

cython3.2.9Compiles the Cython compiler's C extensions. Upstream publishes no riscv64 wheel for 3.2.9 (riscv64 wheels for the newer 3.3.0 already ship via #330's
build-cython.yml, which this PR reuses unchanged).Mirrors upstream's
wheels.yml, same asbuild-cython.ymlalready does for 3.3.0.Differs from upstream
