claude-proxy: native C# GUI to force Claude desktop traffic through a proxy

Windows tray "switch" that routes all Claude MSIX-app traffic through a
SOCKS5/HTTP proxy or a VLESS+Reality tunnel (embedded Xray-core), with a
fail-closed Windows Firewall lock. Runs de-elevated so it launches the
user's normal Claude instance; elevates only for firewall changes.
