The MCP server hardcodes `api.helicone.ai` as the API base URL, which makes it unusable for EU customers whose data lives on `eu.api.helicone.ai`. Add support for `HELICONE_BASE_URL` and `HELICONE_AI_GATEWAY_BASE_URL` environment variables so users can point the MCP server at the correct regional endpoint.
