/*
Sultry - TLS Proxy with Multiple Connection Strategies

Architecture Overview:

1. Pure Tunnel Mode (Primary):
   Client → Client Proxy → [Direct TCP Connection] → Target Server

2. OOB Handshake Relay (For SNI Concealment):
   Client → Client Proxy → [Firewall] → Server Proxy → Target Server
                       ↑                    ↓
                       OOB Channel (SNI hidden)

3. Direct HTTP Fetch:
   Client → Client Proxy → [HTTP Request] → Target Server

The proxy system offers multiple strategies with automatic fallback:
- Pure Tunnel Mode provides the highest reliability and compatibility
- OOB Handshake Relay conceals SNI information from network monitors
- Direct HTTP Fetch efficiently handles plain HTTP requests

By implementing these strategies, Sultry balances security, privacy,
and reliability based on the specific requirements of each connection.
