TCP transport
Adds a raw Arrow-IPC TCP transport to the worker:
Worker.runTcp(host, port, idleTimeoutMs)viaTcpSocketTransport(emits theTCP:<host>:<port>discovery line; idle-timeout self-shutdown).- Worker CLI accepts
--tcp [HOST:]PORT(host defaults to 127.0.0.1), mutually exclusive with--http/--unix. - Bumps the
farm.query:vgirpcdependency to 0.11.0 (raw-TCP socket transport).
Raw TCP framing carries no auth/encryption — loopback/trusted networks only; HTTP remains the transport for untrusted networks.
