feat(prompt): add confirmation fields + edit for clarity (#58)

* chore(config): switch czConfig to config

* feat(prompts): add confirm and clarify language

Breaking changes and issues now have confirm fields to ensure answers like "no" and "n/a" don’t
accidentally create breaking changes. Updated language around scopes to be less confusing for
non-Angular devs. Added examples for issue references/closing.

fix #52

* fix(engine): remove unhandled Promise rejection handler

This was for debugging and should not have been committed.

* refactor: clean up grammar and punctuation
