• Marked the package as private
• Changed cspell dependency from ^9.2.1 to exact version 9.2.1

[Copilot]

The version field in package-lock.json should be removed when the package is marked as private, as shown in package.json. Private packages typically don't need version tracking in the lockfile root.

Suggested change

"version": "1.0.0",

[Copilot]

The packages root entry should include the 'private: true' field to match the package.json configuration and maintain consistency between the two files.
