Rewrite interactive CLI commands

- Replace doom//upgrade with doom/upgrade
- Replace doom//autoloads with doom/reload-autoloads
- Replace doom//refresh with doom/reload
- Remove doom//install; there should be no workflow for this command
- Remove doom//autoremove; autoremove was replaced with purge. Maybe
  I'll write a doom//purge analogue. Not sure yet.
- Use compile instead of hacky wrapper around core-cli API

Rewrite interactive CLI commands

- Rewrite doom//upgrade & doom//autoloads
- Remove doom//install; there really should be no use-case for it
- Remove doom//autoremove; autoremove was replaced with purge. I'll get
  around to writing a doom//purge eventually.
