Adds --smart-rerun, which caches failed test file paths and runs them first on the next invocation, ahead of the rest of the suite. The cache clears automatically once everything passes. Adds --smart-rerun-only-failed (requires --smart-rerun) to skip files that passed last run entirely and only execute previously-failed files, falling back to a full run when the cache is empty or stale. Both flags are off by default and do not change existing behavior. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
