Security Notes

The application makes HTTP requests to external documentation sources, which introduces typical risks of external dependencies. The local development OpenSearch setup (via Docker instructions in README) uses a dummy password and disables security, which is unsafe for production but explicitly for local use. The `RequestLoggingFilter` logs authorization headers at TRACE level for POST requests, which is a potential information disclosure risk if trace logging is enabled in a production environment with sensitive data.
