A couple of small suggestions that could improve the PR:

• Could we add some documentation for the public methods? A short comment above each method explaining what it does and what it returns would be enough. It doesn't need to be detailed, just enough so someone can understand the purpose without reading the implementation
• There are several empty .ts files (for example, GraphBuilder.ts, VectorDatabase.ts, and OllamaProvider.ts). I think it would be better to add these files only when they contain some implementation. This helps keep the repository clean and avoids giving the impression that these parts are already implemented
