CallerIdentity.current(environment:)(environment: [String : String]) -> CallerIdentity?

Reads the surrounding tmux, or `nil` when both context variables are absent.

An incomplete or malformed environment remains present as an invalid
identity so an input guard cannot mistake it for a detached process.
