The guardDaemonStartForDolt check was only applied to the 'bd daemon start'
subcommand, but the deprecated 'bd daemon --start' flag path bypassed it.
This adds the same guard check to the deprecated path so both entry points
consistently refuse to start the daemon when Dolt backend is configured.
The --federation flag still allows Dolt since it enables dolt sql-server
mode which supports multi-writer access.
