* 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>
