Add variant_gcc_false_positive.cpp to reproduce GCC 12+ spurious -Wmaybe-uninitialized warnings when copying/moving variant containing non-trivially-copyable types like std::exception_ptr and std::string. Tests use boost::system::result which internally uses variant2, and include coroutine-based tests when C++20 coroutine support is available. The test uses -O3 optimization to trigger the aggressive inlining that exposes the false positive where GCC's dataflow analysis cannot prove the discriminator ensures only initialized alternatives are accessed.
