Subject: [PATCH 3/3] Optimize CI: Enable test parallelization and rebalance
 integration matrix

- Add -parallel=4 to unit and integration tests for 20-30% speedup
- Remove -count=1 flag to enable test result caching
- Split Workflow integration group (462s) into 4 balanced groups (~150s each)
- Increase integration timeout from 3m to 5m for parallel execution
- Expected total time savings: ~400+ seconds per PR run

Analysis based on 100 recent CI runs showing 462s bottleneck in
monolithic Workflow test group with 5,183 tests.
