Feature request: loop test run until failure for watch mode

Clear and concise description of the problem

sometime we have a flaky test in the suite. We think we have made a change which could fix the flaky spec, but how do we verify this?
You need to run the test like 100x in a row or something. With the current watch mode that would entail hitting enter key manually 100x.

Suggested solution

add run until failure mode to watch usage screen:

then you can just enable this, mode grab a ☕ and come back in a few minutes refreshed to see if the flakyness is fixed or not

Alternative

manually hitting enter key 100x

• Follow our Code of Conduct
• Read the Contributing Guidelines.
• Read the docs.
• Check that there isn't already an issue that request the same feature to avoid creating a duplicate.

Start by tracing the watch mode usage screen and its current run-again interaction. Implement the requested run-until-failure option so a selected test repeats without manual Enter presses, and verify that the mode stops and reports the first failure.
