Fix output printing when Silent option is enabled in SDK

Currently, when using the Naabu SDK with the Silent option enabled,
the scan results are still printed to stdout due to unconditional logging.

This change adds a conditional check around all stdout printing blocks to
respect the Silent flag in runner options.

With this fix, no output will be printed automatically when Silent is true,
allowing users to fully control result output via the OnResult callback.

This improves SDK usability by preventing unwanted console output,
enabling cleaner integration into other tools and pipelines.
