opencrabs 0.3.80

//! Regression (#963): a Homebrew-managed install is recognised as such.
//!
//! `InstallMethod` had three variants and none of them was Homebrew, so a brew
//! install fell through to `PrebuiltBinary`. That path renames a downloaded
//! GitHub asset over the running binary — which SUCCEEDS in a Cellar, because
//! the prefix is user-owned, and leaves brew reporting a version that no longer
//! matches the disk until an unrelated `brew upgrade` silently reverts the user.
//!
//! Detection is path-based on purpose: `brew --prefix` needs brew on PATH,
//! which it often is not in a spawned process, and costs a subprocess to answer
//! what the path already answers.
