pub fn source_label(spec: &str) -> Option<String>Expand description
The provenance label a spec WOULD receive, computed WITHOUT cloning or
network access. Used by znative load <spec> to check whether a source is
already installed (the index keys on this label, since a repo’s basename
often differs from its znative.toml plugin name — e.g. zshrs-forgit →
forgit). Returns None for a bare plugin name (not a source form).
