Function default_ci_token 

pub fn default_ci_token(
    forge: Forge,
    var: impl Fn(&str) -> Option<String>,
) -> Option<&'static str>

The default CI token’s variable, where the credential the forge CLI would push with is that token alone.

A push made with the default token starts no pipeline, so the release half would never run. GH_TOKEN and GITLAB_TOKEN carry the bot credential; a job that sets only GITHUB_TOKEN or CI_JOB_TOKEN, or sets the bot variable to the same value, pushes as the default token.
