feat(agent): enhance reasoning handling and configuration

Added support for processing encrypted reasoning content within the AIAgent class. Introduced logic to determine reasoning effort and enable/disable reasoning based on configuration settings. Updated the kwargs to reflect these changes, ensuring proper handling of reasoning parameters during agent execution.
