Function cli_external_manager_name

src/cli/cli.c:9455–9476

Is the running binary owned by an external package manager rather than by us? * * #1566: cbm's installer does two separable jobs — place the binary (and put its * directory on PATH), and configure the agents. For someone who installed * through mise, Homebrew or nix, the first job is not merely redundant: it drops * a SECOND copy into ~/.local/bin that shadows the managed one depending on PAT

 * best-effort — the behaviour does not depend on recognising it, only the
 * wording does. */
