// runUpdate executes the brew-or-download upgrade against targetVersion and
// returns the human-readable output (always populated, even on failure when
// brew gives us a useful diagnostic). The caller is responsible for the
// `updating` CAS guard and for reporting status back to the server / triggering
// the restart — extracted so the server-triggered path (handleUpdate) and the
// auto-update poller (autoUpdateLoop) share the exact same execution body.

// both features have the same user-visible failure mode: the daemon completed

// server-side request times out.
//
// Overridable for tests to avoid real sleeps.
