Introduces a TCP-socket-like abstraction for mixnet communication: - MixSocket: unconnected socket that can be connected or used as listener - MixStream: bidirectional stream with send/recv methods - MixStreamReader/MixStreamWriter: split halves for concurrent I/O - NetworkEnvironment: helper for loading environment configs Uses SURBs for anonymous replies when operating in listener mode.
Adds methods to query exit-capable gateways from the nym-api: - get_all_basic_exit_assigned_nodes_with_metadata: paginated fetch - get_basic_exit_assigned_nodes_v2: single page query Used by IpMixStream for automatic gateway selection.
IpMixStream wraps MixStream to tunnel IP packets through Exit Gateway IPRs (IP Packet Routers), enabling use of the mixnet as a proxy for regular internet traffic. The ip_packet_client module contains IPR connection and protocol logic forked from nym-ip-packet-client and adapted for SDK use: - IprClientConnect: handles IPR connection establishment - IprListener: processes incoming IP packet responses - Helper functions for IP packet construction/parsing (ICMP, etc.) - Error types for IPR operations
Updates lib.rs doc comments and README.md to describe new modules: - stream_wrapper: socket-like abstraction (MixStream, IpMixStream) - Marks tcp_proxy as deprecated in favor of stream_wrapper

Part 2 of breaking #6129 into smaller chunks.
This is the second (so should only be looked at after #6318 is merged and this branch is rebased, removing the first chunk of commits).
This contains the nym client -> nym client Rust SDK stream wrapper, and the stream wrapper for the Rust SDK which uses gateway IPRs to send IP packets through the mixnet.
This change is
