Use POSIX shm_open instead of a /tmp file for the EventState shm — RAM-backed on Linux (/dev/shm) and macOS (POSIX shm namespace). FIFO paths stay in /tmp since FIFO data lives in kernel pipe buffers, not the filesystem. macOS limits shm_open names to ~31 chars, so hash (prefix, identifier, endpoint) into a fixed `/msgq_<16 hex>` name. macOS also rejects ftruncate on an already-sized shm object, so check the size first.
CI was failing on Linux: a stray signal delivered to the forked daemon during poll returned EINTR, which my code propagated as a runtime_error, killing the daemon. Master's ppoll+sigmask blocked most signals so EINTR never came up in practice. Switch to a deadline-based poll wrapper that retries on EINTR, and add the same retry to set()/clear().
