Module install 

How this binary was installed, and therefore which command updates it.

codewhale update replaces the running executable in place. That is the right thing for a binary the user downloaded from GitHub Releases, and the wrong thing for one a package manager owns: overwriting Homebrew’s Cellar binary or npm’s node_modules payload leaves the manager’s metadata describing a version that is no longer on disk, and the next brew upgrade / npm install -g silently reverts the user.

So before we tell anyone to run anything, we work out who owns the file. Detection is path-based (plus an escape-hatch env var) because the install method is a property of where the binary lives, which is knowable offline, in a test, and without asking a package manager anything.
