/**
 * @file Tests the `tmux` row of scripts/plugin-doctor.js — the check that tells
 * an install its browser run console cannot work, because every run the
 * dashboard starts is a tmux session (server/lib/tmux.js). The row must WARN
 * and never FAIL: sessions, analytics, lanes and the CLI all work without the
 * binary, so failing a doctor run over it would cry wolf. tmux is faked through
 * the module's own exec seam, so the test never depends on the host having it.
