refactor(cli): colocate --help examples in command files (#202)

Move per-command examples from the centralized `help.ts` record into
each command file as `export const examples: Example[]`. help.ts now
dynamically imports them at --help time.

This means adding a new command and its examples happens in one file
instead of two, reducing the chance of forgetting examples.
