💪 Performance improvements for gpt-4o and gpt-4o-mini

Improved compatibility with gpt-4o and gpt-4o-mini models: We updated the prompt format for weaker models so that the inner thoughts of the agents are properly generated (previously, these models could only generate None for inner thoughts).

🐛 Bugfixes for the CLI

Fixed issues with creating, listing and deleting humans and personas.
