Recover the signatures from the 11.00 module wrappers and implement InitializeWithPort, the per-context custom property, the peer-address group lookup, the internal callback registration, the memory information and the connection statistics. The host stores the pool size and the property, reports zero usage and statistics for the offline runtime, and still throws for the signaling paths that need the network. A destroyed context slot clears the property and both callback pointers before it is reused, so a new context starts from a fresh state.
