build: move from pnpm to npm

Replace pnpm-lock.yaml with package-lock.json.

pnpm-workspace.yaml pinned npm only where cubejs depends on it
("cubejs>npm: ^11.14.1"). npm expresses that path scoping with a nested
override, so the pin stays scoped to cubejs instead of applying to every copy of
npm in the tree. Verified: cubejs is still the only overridden path.
