[compiler] Improve snap workflow for debugging errors (#35539)

Much nicer workflow for working through errors in the compiler:
* Run `yarn snap -w`, oops there are are errors
* Hit 'p' to select a fixture => the suggestions populate with recent
failures, sorted alphabetically. No need to copy/paste the name of the
fixture you want to focus on!
* tab/shift-tab to pick one, hit enter to select that one
* ...Focus on fixing that test...
* 'p' to re-enter the picker. Snap tracks the last state of each fixture
and continues to show all tests that failed on their last run, so you
can easily move on to the next one. The currently selected test is
highlighted, making it easy to move to the next one.
* 'a' at any time to run all tests
* 'd' at any time to toggle debug output on/off (while focusing on a
single test)
