Monthly summary for May 2025 (fair-acc/gnuradio4): Stabilized builds and delivered dynamic graph topology enhancements for OpenDigitizer. Key changes include moving topology-change messaging to the Scheduler, introducing a Zombie list for graceful removal of blocks, enabling adding blocks to a running scheduler, and loading graph configurations from YAML. A critical build fix ensures executables link against a single C++ standard library, preventing libc++/libstdc++ mixing.
