Harden PDF loading against edge cases#1
Conversation
Identified and handled several edge cases in `load_pdf`: - Added type validation for input path. - Added check to ensure path is a file, not a directory. - Added explicit check for encrypted PDFs. - Wrapped PyMuPDF (fitz) open call to gracefully handle corrupt files and raise clearer ValueErrors. Added `tests/test_edge_cases.py` to cover: - Encrypted files - Corrupt files - Wrong input types - Directory paths - Image-only and empty files

- Update `load_pdf` in `src/docblocks/io/pdf_reader.py` to handle edge cases:
- Validate input type (must be string).
- Ensure path is a file (not a directory).
- Check for file existence.
- Check for `.pdf` extension.
- Handle corrupt files by catching `fitz` exceptions.
- explicit check for encrypted PDFs.
- Add `tests/test_edge_cases.py` to test these scenarios.
- Remove `tests/test_run.py` (manual test script).
- Add `.github/workflows/publish.yml` for automated PyPI publishing on release.
Identified and fixed edge cases in PDF loading including encryption, corruption, and invalid inputs. Added comprehensive tests.
