[WIP] Fix connection issue with uvloop and SOCKS5

[Copilot]

Fix uvloop + SOCKS5 Connectivity Issue

Analysis

• Understand the issue: uvloop is incompatible with SOCKS5 socket monkey-patching
• Determine solution: Disable uvloop when SOCKS5 is configured
• Implement fix in try_setup_uvloop() to check for SOCKS5 configuration
• Update documentation to reflect the incompatibility
• Test the fix manually
• Run code review
• Run security checks

Root Cause

The issue occurs because:

1. apply_upstream_proxy_settings() patches socket.socket with socks.socksocket
2. try_setup_uvloop() is called afterwards and sets up uvloop's event loop
3. uvloop's native socket implementation conflicts with the monkey-patched SOCKS socket
4. This causes connection failures when both features are enabled

Solution

Modified try_setup_uvloop() to detect SOCKS5 configuration and skip uvloop setup when SOCKS5 is active. When SOCKS5 is detected, a clear message is printed: "SOCKS5 proxy is configured, skipping uvloop (incompatible)"

Pull request overview

This PR fixes a critical incompatibility issue between uvloop and SOCKS5 proxy configuration. The root cause is that SOCKS5 implementation monkey-patches socket.socket with socks.socksocket, which conflicts with uvloop's native socket implementation, causing connection failures when both features are enabled simultaneously.

Key Changes:

• Added a pre-check in try_setup_uvloop() to detect SOCKS5 configuration before setting up uvloop
• When SOCKS5 is active, uvloop setup is skipped with an informative error message
