 **Supported protocols:** `socks5://`, `socks5h://`, `http://`, `https://`, all with embedded authentication (`user:pass@host:port`).

+**Optional parameters:**
+- `proxyIp` — provides the proxy's exit IP to skip automatic IP detection, resulting in faster geo-based timezone and language adaptation.
+- `proxyBypassList` — semicolon-separated list of hosts/patterns that should bypass the proxy (e.g., `localhost;*.internal.com`).
+- `proxyBypassRgx` — regex pattern (RE2 syntax) for URLs that should bypass the proxy. Supports `|` for multiple patterns (e.g., `cdn\.example\.com|/api/health`).
