Thanks @felixarntz for the PR! It looks solid.

Can we also consider removing certain functions and text associated with SQLite?

• Activate and deactivated module code that introduce through module integration that we did not use for any other module.
  • perflab_run_module_activation_deactivation()
  • perflab_activate_module()
  • perflab_deactivate_module()
  • 'update_option_' . PERFLAB_MODULES_SETTING action
  • 'add_option_' . PERFLAB_MODULES_SETTING action
• Remove SQLite Integration from readme.txt

@mukeshpanchal27 While the functions you reference were added as part of the SQLite PR, they are generally applicable and part of the infrastructure itself, as they could be useful for any module in the future. So I think we should keep them.

Regarding the readme.txt update, this will be taken care of automatically as part of the release process, via npm run readme.
