pub fn workspace_metadata(root: &Path) -> Result<String, String>Expand description
Runs cargo metadata --no-deps --format-version 1 in root and
returns its JSON, for feeding to blast_radius.
Shells out rather than linking a manifest parser, the same posture the
workspace takes with curl, openssl, and mergiraf. --no-deps
keeps it offline: registry packages are never resolved.
ยงErrors
Returns a description if cargo cannot be spawned or exits nonzero.
