Fix release build crash when semver has no prerelease/build suffix

split_semver returns None for prerelease and build on clean versions
like 1.5.0. These None values were passed into serialize_cpp_define
which called int(None), raising a TypeError that crashed all CI builds.

Skip setting the CPP defines when prerelease/build are absent, and add
#ifndef fallback guards in WSGateway.cpp to default them to nullptr.
