Pull request overview
This PR hardens the CircleCI test pipeline against corrupted sccache state by detecting the specific “sccache ... (exit status: 2)” failure mode, wiping local cache artifacts to prevent re-saving a poisoned cache, and retrying once from a clean state. It also bumps the cache key version to proactively invalidate the currently failing cache (per issue #3304).
Changes:
- Bump all CircleCI cache key prefixes from
v4.7.2tov4.7.3to invalidate existing caches. - In the
run_test“Run Tests” step: capture failures, detect thesccacheexit-status-2 crash signature, wipe local cache/build state, and retry the test run cleanly. - Minor comment punctuation fix (“flags, they” → “flags, they”).

The intent of this PR is to wipe the cache whenever it gets corrupted, so that it doesn't get saved in that state. In addition, the current cache - apparently borked - is discarded due to its version bump.
Fixes #3304.
