 * A custom evaluator for Amazon Bedrock AgentCore.
 *
 * Custom evaluators enable you to define evaluation logic tailored to your specific
 * use cases. Supports two evaluation strategies:
 * - **LLM-as-a-Judge**: Uses a foundation model with custom instructions and a rating scale.
 * - **Code-based**: Uses a Lambda function for custom evaluation logic.
 *
 * Custom evaluators are used with `OnlineEvaluationConfig` via `EvaluatorSelector.custom()`.
 *
 * @resource AWS::BedrockAgentCore::Evaluator

 * @example
 * // Create a custom LLM-as-a-Judge evaluator
 * const evaluator = new agentcore.Evaluator(this, 'MyEvaluator', {
