Calls are executed in one of two ways:

 * **Synchronous:** your thread blocks until the response is readable.
 * **Asynchronous:** you enqueue the request on any thread, and get [called back](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-callback/) on another thread when the response is readable.

 * This class provides support for executing Groovy scripts with parameter binding
 * and DI container integration.
 *
 * <p>Thread Safety: This class is thread-safe. Each evaluate() call creates
 * a new GroovyShell instance to ensure thread isolation.</p>
 *
 * <p>Resource Management: GroovyClassLoader instances are properly managed
 * and cleaned up after script evaluation to prevent memory leaks.</p>
