* Add SOCKS5 proxy support via pluggable stream provider Introduces MQTTnet.Extensions.Socks5, enabling SOCKS5 proxy support for MQTTnet TCP transport. Adds IMqttClientStreamProvider interface, Socks5StreamProvider implementation, and related configuration options. Updates MqttTcpChannel to support stream providers and TLS layering. Includes unit tests with a fake SOCKS5 server and usage samples. Solution and project references updated accordingly. * Add SOCKS5 options validation for invalid configurations * Tighten SOCKS5 RFC compliance checks --------- Co-authored-by: Copilot <Copilot@users.noreply.github.com>
