Contributions summary:Glenn's primary contribution focused on implementing a feature to disable agents within the Huginn system. This involved adding a `disabled` attribute to the `Agent` model and creating corresponding database migrations. The user also updated the user interface across multiple views (index, show, and form) to include the ability to disable and enable agents, including related actions in the action menu. Furthermore, the user updated the agent diagrams to reflect the disabled state, ensuring that disabled agents are correctly represented in the system. Finally, the user adjusted various related logic to accommodate and handle the new disabled agent state.

Contributions summary:Glenn refactored and reorganized core functionality by separating the command-line interface from the core library (`libgobuster`). This involved moving state initialization, validation, and error handling into separate helper functions to improve code modularity and maintainability. The changes demonstrate a focus on improving the project's architecture and preparing it for use as a library.
