changelog:
- add new nostr url format that works better for MacOS users
`nostr://<*protocol>/<npub123>/<*relay-hint>/<identiifer>`
\*optional
- 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)
- enable building binaries via nix
- refactor into lib and bin structure
- bump dependencies
