Enhance OllamaAPI and documentation for structured responses

- Updated OllamaAPI to return an instance of OllamaResult instead of OllamaStructuredResult for structured responses.
- Removed the obsolete OllamaStructuredResult class.
- Added new methods in OllamaResult for retrieving structured responses as a Map or mapped to a specific class type.
- Updated integration tests to validate the new structured response functionality.
- Improved Makefile with a new full-build target for building the project.
