test(integration): add enhanced duration metrics tests
Add integration tests for Lambda enhanced duration metrics to verify that runtime_duration, billed_duration, duration, post_runtime_duration, and init_duration metrics are correctly emitted across runtimes. Changes: - Add ENHANCED_METRICS_CONFIG and getEnhancedMetrics() to utils/datadog.ts - Extend invokeAndCollectTelemetry to return RuntimeTelemetry with metrics - Add duration metrics tests to on-demand.test.ts for all runtimes - Update lmi, otlp, snapstart tests for new RuntimeTelemetry return type Tests gracefully skip when metrics data isn't available in query window. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
