scc-cli 0.2.11

//! `scc update` self-update tests: the command resolves through the same
//! installer mechanism `docs/INSTALL.md` documents, against a fixture
//! release layout (no network). A fixture `SCC_DOWNLOAD_BASE` with a
//! pinned --version must dry-run cleanly and print the installer's plan.
