Detailed Description

Head-to-head benchmark: FairMQ shmem transport vs memfd+UDS fd passing.

Self-contained single-file benchmark using fork() for sender/receiver. Approach A: FairMQ shmem push/pull channel with per-message allocation Approach B: memfd (Linux) or shm_open (macOS) + bump allocator + UDS SCM_RIGHTS
