* 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

When a publish, subscribe or unsubscribe request was cancelled or
timed out client-side, the corresponding awaitable was removed from
the packet dispatcher. A subsequent PUBACK / PUBCOMP / SUBACK /
UNSUBACK arriving from the broker then fell through to the default
case and raised an MqttProtocolViolationException, which forced a
disconnect. Under high publish load (issue #2079) and from multiple
threads (issue #2078) this manifested as sporadic connection drops.
Match these acknowledgement packets explicitly and log a warning
when no awaiter is registered, instead of treating it as a protocol
violation. The connection is now preserved.
Also documents the thread-safety guarantees of IMqttClient: publish,
subscribe, unsubscribe and ping operations are safe to invoke
concurrently. Connect / disconnect must still be coordinated.
