Update Go module dependencies and enhance assistant message handling in Neo API

- Added the github.com/spf13/cast dependency to improve type conversion capabilities.
- Enhanced the requestMessages function to include prompts, allowing for more dynamic message handling.
- Updated the LoadBuiltIn function to ensure the "Built-in" tag is added if it doesn't already exist, improving assistant organization.
- Refactored sorting logic to utilize the cast package for better type safety.

These changes support improved functionality and maintainability in the assistant management process.
