- usage-limit-detector + provider-health-monitor: make three bare listTasks()
callers explicit with { slim: true }, restoring the architecture-hot-paths
contract (they only read scalar pause/column/model-provider fields).
- pg-test-harness beforeEach: wipe <rootDir>/.fusion/tasks after TRUNCATE ...
RESTART IDENTITY so filesystem isolation matches the id reset; stale task
dirs from prior tests no longer collide with reused IDs (fixes
store-reservation-atomicity rollback assertions).
