Update package-lock.json (#155)

[Created by Copilot on behalf of @bghgary]

Update `package-lock.json` to include resolved optional dependencies.

`npm install` was regenerating the lock file on every run because
`fsevents` (an optional macOS dependency) was missing. This caused
spurious diffs when working locally.
