Skip socket base module in processor scan

Update processor package discovery to ignore `dlc_processor_socket` during namespace scanning, since it only provides the base class/registry and should not be listed as an available processor source. The package fallback scan now uses default class discovery behavior, and related outdated comments/docstring lines were cleaned up.
