- status updates during clone, push and fetch
- intelligent protocol selection and fallback
  - unless unusual protocol specified in clone url it will try
    in this order:
    - fetch: https unatuth, ssh, https
    - push: ssh, https auth
  - save successful protocol in git config so it is tried first
    next time
  - enable override from nostr url (will only use this protocol)
