devalue rejects Error objects, so when a NODE_RUNTIME_INCLUDE test file
failed to load, the pool's send() threw DevalueError and the run ended
without a summary. Give both ends of the IPC channel one codec with a
matching Error reducer/reviver (name, message, stack, cause) so the load
failure reaches the reporter as a normal FAIL.
Fixes#29854
