## Title

    Use the evaluator status fix for lower-is-better metrics in ADK 2.13.0

## Body

    Evidence basis: public_source. This finding was not independently executed. A reporter observed that a lower-is-better evaluator returned PASSED while AgentEvaluator.evaluate() reported FAILED on google-adk 2.11.0: https://github.com/google/adk-python/issues/7414 The reporter describes a before-and-after test of the related change. The official 2.13.0 release lists commit 5bf7f12: https://github.com/google/adk-python/releases/tag/v2.13.0 The released implementation infers metric direction from scored invocation statuses and compares the mean with the threshold.
