Until now `package-lock.json` was globally ignored. Two practical
consequences for the Node binding:
- A fresh `git clone && cd bindings/node && npm install` resolved
`@napi-rs/cli` and any transitive deps to whatever the npm registry
currently considered the latest matching the package.json semver
ranges. Contributors could get different dep graphs on different days.
- No protection against transitive-dep tampering at install time
(lockfile records resolved versions + integrity hashes, npm verifies
on subsequent installs).
Drop the global `package-lock.json` ignore and commit the freshly
generated `bindings/node/package-lock.json` (140 lines, only a couple
of direct deps because the binding is small). The `.gitignore` comment
notes that we still don't expect lockfiles at the workspace root.
No CI workflow changes — the existing `npm install` in the Node-test job
will now consume the committed lockfile, which is exactly what we want.
