Proxy support
The plugin now connects directly first and automatically falls back to a configured HTTP proxy — from your http(s)_proxy environment variables or the Windows system proxy — if the direct connection fails. No settings required.
This fixes connection failures on machines where a proxy environment variable is set (common in some regions and corporate networks), where the connection previously failed even with the proxy turned off.
🙏 Huge thanks to @JohnCido for the detailed testing and the test matrix that pinned this down — it made the root cause easy to find.
