Flaky StreamingToolTest failure on main branch

https://github.com/google/adk-java/actions/runs/17123110179/job/48568418331?pr=373 for https://github.com/google/adk-java/pull/373/files, which is a trivial change that could not have caused this, failed with:

Error:    StreamingToolTest.runLive_videoStreamingTool_receivesVideoFramesAndSendsResultsToLlm:343 missing (3): Function monitorVideoStream returned: {people_count_alert=Processed frame: detected 2 people} [3 copies]

expected   : [Function monitorVideoStream returned: {people_count_alert=Processed frame: detected 2 people}, Function monitorVideoStream returned: {people_count_alert=Processed frame: detected 2 people}, Function monitorVideoStream returned: {people_count_alert=Processed frame: detected 2 people}]
but was    : []

But e.g. #363 and #371 built just fine.

So it looks like that's a flaky test?

Yeah, it went away simply by re-running that build.

@Poggecci looks like StreamingToolTest was introduced by you in #323, do you want to have a look at this?
