3 people 7f928f9f8e fix(parse): warn when PDF parse yields no text layer (scanned PDFs) (#1021) ...

* fix(parse): import email.message and repair pdfplumber test mock

- email_parser.py uses email.message.Message at class-definition time but
  only did 'import email', so 'import semantica.parse' fails in a fresh
  Python process unless something else imported email.message first
- test_pdf_parser patched semantica.parse.pdf_parser.pdfplumber, which
  never exists as a module attribute (pdfplumber is imported inside
  PDFParser.parse); inject a fake module via sys.modules instead

* fix(parse): warn when PDF parse yields no text layer (scanned PDFs)

Scanned (image-only) PDFs parsed via the default pdfplumber route
returned an empty full_text with progress status 'completed' - no error,
no warning - so the failure only surfaced far downstream. Warn in
PDFParser.parse() when every parsed page yields no text (and extract_text
is enabled), pointing users to method='docling' with enable_ocr=True.

* fix(parse): improve scanned PDF detection
