 * already complete and valid, only its dependencies are missing. Returns whether it succeeded so
 * callers can adjust what they tell the creator to do next — `bitmagic check` cannot run without
 * node_modules.
 *
 * The manager is chosen per machine rather than fixed (`preferredInstallManager`), and named out
 * loud on the way past: which one ran decides the lockfile, and the lockfile decides what every
 * later command tells this creator to type.
