Feature Request: Runtime proxy configuration command

Summary

Add a runtime command (e.g., /proxy or /network) to change proxy settings without restarting Claude Code.

Problem

Currently, proxy settings can only be configured via environment variables or settings.json before launching Claude Code. If the network environment changes during a session (e.g., connecting/disconnecting from VPN, moving between office and home), users must:

1. Exit Claude Code
2. Change environment variables or settings
3. Restart Claude Code

This is disruptive, especially during long sessions or when frequently switching networks.

Proposed Solution

Add a slash command like:

/proxy set https://proxy.example.com:8080
/proxy clear
/proxy status

Or integrate into existing settings:

/config set HTTPS_PROXY https://proxy.example.com:8080

Use Cases

• Switching between corporate VPN and direct connection
• Temporarily bypassing proxy for specific tasks
• Debugging network issues without losing session context

Alternatives Considered

• Shell aliases for different proxy configurations (still requires restart)
• direnv for directory-based settings (still requires restart)
• Wrapper scripts (still requires restart)

All workarounds still require restarting Claude Code.
