- Add decode_page_content_streams() function for per-page lazy decode
- Update extract_page_from_dict() to support lazy stream decoding
- Modify extract_pdf() and extract_pdf_ndjson() to enable lazy decoding
- Fix borrow checker issue in LazyPageIter::next()
This ensures content streams are decoded lazily per page and dropped
immediately after processing, keeping peak RSS flat across page count.

- Updated test_api_null.c to run 10,000 alloc/free cycles (was 100)
- Updated verification note to mark memory roundtrip as PASS
- Improved stream_next implementation to use reference-based approach
instead of Box::from_raw/leak dance for cleaner memory handling
All acceptance criteria for pdftract-5ya9x now PASS:
- 12 exported symbols verified via nm -D
- C client tests (test_api.c, test_api_null.c)
- C++ client test (test_extract.cpp)
- Null pointer safety
- Panic safety (catch_unwind on all entry points)
- Memory roundtrip (10,000 iterations)
- Thread safety (8 pthreads)
