Align engines.node with the .nvmrc 24.2.0 pin so npm/pnpm warn on
mismatched local toolchains, move packageManager to the current
pnpm 9.15.3 patch, and ignore pnpm's local store and debug log so
stray artefacts never get committed.
Vitest 2 pulled Vite 5 + esbuild 0.21 (GHSA-67mh-4wv8-2f99). Bumping
vitest/@vitest/ui to v3 and adding vite ^6 as a direct dev dep forces
peer resolution onto Vite 6 + esbuild 0.25, which also clears the Vite
path-traversal advisory (GHSA-4w7w-66w2-5vf9). pnpm audit is now clean.
