Enhance OASIS simulation capabilities and profile generation

- Updated README.md to include detailed descriptions of new features, including Zep mixed search functionality and detailed persona generation for individual and group entities.
- Implemented a robust mechanism for checking simulation preparation status to avoid redundant profile generation.
- Added support for parallel profile generation, improving efficiency in creating OASIS Agent Profiles.
- Enhanced the simulation configuration generator to adopt a stepwise approach, ensuring better handling of complex configurations.
- Introduced error handling and retry mechanisms for LLM calls, improving the reliability of profile generation.
- Updated simulation management to support new API parameters for controlling profile generation behavior.
