Warn if archetype implements any `npm` lifecycle tasks

[coopy]

See: https://docs.npmjs.com/misc/scripts

• test
• start
• preinstall
• postinstall
• preversion
• postversion
• etc

Task:

• [ ] Implement warning in builder or maybe builder-support
• [ ] Scour and fix all of our existing archetypes that have these (we've definitely got test lurking around).

Additional use cases:

• [ ] Want to use prepublish or something, in an archetype. Should switch above implementation to ignore the npm lifecycle commands.
