Faster commands when the Tuist server is slow: bounded run metadata uploads

Best-effort run metadata uploads now run under a 15-second total deadline in both the continuous integration foreground path and the hidden local background-analytics command, so tuist install and similar commands no longer linger on a slow or unhealthy server. Required uploads that produce report links and CI job summaries keep their previous behavior, and retry-driven server calls now respect the upload deadline via task cancellation rather than running in a detached task.
