Install footprint and published tarball
Each version installed on its own into an empty project with nothing but @nuxt/cli as a dependency, so the tree is exactly the CLI and its transitive dependencies. npm cache is warm and the registry is only consulted for metadata, so install wall time is indicative, not a network benchmark.

Interleaved runs on a shared runner: trust the deltas, not the absolute timings. The dev, restart and build suites run locally via pnpm bench:cli.

- Line 67: Add the pinned actions/setup-node step with node-version 24 before
pnpm/setup in both .github/workflows/autofix.yml (lines 67-67) and
.github/workflows/cli-bench.yml (lines 40-40), so direct TypeScript execution
uses the project’s required Node version.

Use the project’s Node version for direct TypeScript execution.
Both jobs use the runner’s ambient node binary. Neither job configures actions/setup-node, and the direct commands bypass pnpm’s runtime management. The project declares Node ^24.0.0, but ubuntu-latest can provide a different version. A Node version below 22.18.0 also rejects flagless .ts execution.
Add the pinned actions/setup-node step with node-version: 24 before pnpm/setup in both workflows.
