Pull request overview
Adds explicit error handling for Grobid failures so the Streamlit UI can surface a clear “please try later” message instead of failing ambiguously (issue #11).
Changes:
- Introduce
GrobidServiceErrorand raise it when Grobid errors or returns non-200. - Catch
GrobidServiceErrorin the Streamlit upload/embedding flow and display an error message. - Add a (currently redundant) guard in
DocumentQAEnginefor missing Grobid output.

There is a missing space, the rest looks fine. I did not test it, so please make sure you tested it before merge/squash.

Yes, @Sanakhamassi here you need to either add tempFile in the with () or handle that somehow
