Stream sockets are not required to return the full requested count from recv(), but the 4-byte length prefix on the supervisor↔subprocess socket was read with a single sock.recv(4). On a short read, the parsed length is garbage, which either raises msgspec.DecodeError in the subprocess or silently deadlocks the supervisor's selector reader (length_needed=0 makes the falsy payload check skip forever, so no frame is ever dispatched to handle_requests). Accumulate the header bytes on both sides, mirroring the payload accumulation that was already correct. Add regression tests using a socket that returns 2 bytes at a time to reliably reproduce the short read.
