Provide a way to reduce the noisy output when running extension tests to reduce context bloat and agent confusion

[DanTup]

When I run extension tests on GitHub actions, there's a lot of unwanted output printed. When trying to have agents run the tests, this all ends up in the context and the model sometimes attribute failures to these "errors".

For example here's all the output before my tests start running. Many of these "errors" are not relevant and don't affect the tests at all. There's also some output duplicated, and the ID of every extension is printed multiple times.

While this output might be useful in some cases, 99% of the time it's irrelevant and some kind of --quiet flag to hide it would help (both LLMs, and users reviewing logs to see their test failures).

Found --crash-reporter-directory argument. Setting crashDumps directory to be '/home/runner/work/Dart-Code/Dart-Code/.crash_dumps/not_activated/flutter_create'

@bpasero, could you please assist with triaging this issue? Thanks!

[bpasero]

I agree, I am having a very hard time to digest actual test output from spam.
