Update to Node 22 (major bump)

[ecraig12345]

just-scripts and just-task will require a major bump soon to allow continued security updates to dependencies.

• Update engines.node to >=22.18.0
• Update dependencies
• Enable esModuleInterop
• Update docs to indicate current status of project, why we mostly recommend lage instead, and avoiding footguns of just config setup (must delay load deps) if people still want to use it
• Copy instructions should copy by default #702
• Consider removing deprecated stuff (focusing on things that are dangerous or significantly in the way)
• Major bump packages: align versions to v3 for clarity, and update beachball config to disallow major bumps
