Function resolve_identity_name

atomic-cli/src/commands/auth.rs:524–526

Extract the identity name from a remote URL alone (no server config). Tries URL userinfo first (`bob@host`), then the subdomain (`bob.host`). This is the config-free path; [`resolve_identity_name_with_override`] layers the `--identity` override and configured server bindings on top.

fn resolve_identity_name(remote_url: &str) -> Option<String> {
    resolve_identity_from_url(remote_url, &[])
