Preserve missing-command detection for Droid probes

When the Droid provider checks a missing CLI, DroidProvider still converts the failure to const message = ... and calls isCommandMissingCause({ message }); after this change that wrapper is no longer recognized, so ENOENT/not found failures are reported as an installed-but-failing Droid CLI instead of "not installed". Either keep supporting the legacy message-shaped input or update the Droid probe to pass the original ProviderCommandNotFoundError/PlatformError into this helper.
