Add support for field selection in assistant filtering

- Implemented `select` parameter parsing in `parseAssistantFilter`
- Added support for selecting fields via string, string array, or interface array
- Enhanced `neo/process.go` to handle flexible field selection
- Improved error handling in stream chat processing
- Fixed function message handling in message appending
