test(pdftract-2bpf6): add FlateDecode predictor tests and proptests
Add missing tests for FlateDecode predictor functionality:
- test_png_predictor_14_rgba_paeth: Verify PNG predictor 14 (Paeth) on 8-bit RGBA
- test_flate_decode_performance_100mb: Performance benchmark (100 MB < 250 ms in release)
- proptest_flate_decode_no_panic: Random byte sequences never panic
- proptest_flate_decode_with_predictor_no_panic: Random predictor params never panic
- proptest_flate_decode_bomb_limit_no_panic: Bomb limits never panic
All acceptance criteria for pdftract-2bpf6 now PASS:
- PNG predictor 15 with all 6 selector types: byte-perfect
- Simple FlateDecode: byte-perfect round-trip
- TIFF predictor 2: 8-bit RGB delta-decoded correctly
- PNG predictor 14 (Paeth) on RGBA: correct output
- Truncated stream: returns partial bytes
- Bomb limit: 3 GB → 2 GB truncation
- Performance: < 250 ms for 100 MB (release mode)
- proptest: 256 random cases × 3 tests, no panics
- INV-8: all error paths return partial bytes
