concoredocker.hpp missing shared memory transport, only file + ZMQ exist #486
Description
concore.hpp has file, shared memory, and ZMQ. concoredocker.hpp only has file and ZMQ, shared memory was never ported over.
Docker on Linux supports shared memory fine (--ipc=host or named shm volumes), so there's no reason to leave it out. All the SHM logic already exists in concore.hpp, it just needs to be brought over, handle members, createSharedMemory/getSharedMemory, read_SM/write_SM, constructor detection, destructor cleanup, and dispatch routing in read()/write().
