Module load cost
Counted with a module.registerHooks load hook, compile cache disabled. Counts every JS module actually evaluated on that code path (built-ins excluded, native addons excluded).

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.

TUI quit and session interrupt handling check this state. When shutdown is not adopted, these paths exit with code 130. The session handler tears down while keeping the terminal. Tests cover SIGINT behavior before and after adoption. Priority: ⬇️ Low Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: ⚪ Minimal · up to Early Ctrl-C and SIGTERM have the intended exit codes; no actionable merge-blocking risk remains after normal checks. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

triggering signal and, when shutdown has not been adopted, exit with status 143
for SIGTERM while preserving status 130 for SIGINT.
