Local single-package runs were single-threaded due to defaultCap: 1; bump
to 3 so iterative `pnpm --filter @fusion/dashboard test` actually uses
available cores (workspace runs still clamp via FUSION_TEST_TOTAL_WORKERS).
CSS transform was applied to every file via /.+/ but only jsdom-environment
tests under app/** read computed styles. Restrict include to /app\// so
node-env src/** tests skip the CSS pipeline.
Wall time on the dashboard suite drops from ~205s to ~148s (-28%).
