This fixes cache propagation delay issues with Blacksmith's distributed cache. The previous implementation used separate save/restore actions with fail-on-cache-miss: true, which failed when the cache wasn't immediately available after being saved by the Prepare job. The new implementation uses actions/cache@v4 (combined save/restore) with a fallback to do the checkout if cache miss, matching the pattern used by cache-build and cache-db which don't have this issue. Changes: - Refactored cache-checkout action to use actions/cache@v4 - Added fallback checkout step when cache miss occurs - Removed mode input (no longer needed) - Updated all workflows to use the simplified cache-checkout action Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>
