This PR gives brokered IPv4 TCP and UDP sockets an internal guest network where 127/8 and the configurable private guest address, defaulting to 10.0.2.15, route between guest programs while host loopback is hidden behind the independently authorized gateway 10.0.2.1. It adds exact-before-wildcard shared guest namespaces, trusted TCP source and accept leases, Linux private-backend isolation on 127.0.0.2, protocol-specific gateway policy and host-loopback translation, bounded route-specific UDP endpoint, readiness, and error lifecycles, deployment configuration, and core, reactor, syscall, and runner coverage.
