Grouping CrewAI

[YamonBot]

I believe that eventually all features of CrewAi should be integrated into Langflow, allowing it to completely replace CrewAi. Recently, CrewAI elements merged into the main code are classified at the same level as other components. However, I think CrewAI should be managed in a separate folder (preferably as a plugin). This does not mean removing CrewAI entirely, but rather that CrewAI should not dominate.

Langflow should be totally modular, agreed.
