"""Tool source/label formatting shared by ``surfaces/cli`` and ``surfaces/interactive_shell``.

Both surfaces render the same live tool-call activity (a source badge like
``Grafana`` or ``SRE``, and a short human label with the source prefix
stripped) while an investigation runs. The two implementations were
identical, so this is the T-21 extraction: pure formatting with no
surface-specific state, safe to share.
