chore(bf-a8031): remove tracked debug/scratch artifacts and compiled binaries
Remove 40+ tracked scratch artifacts violating the normative file layout:
- Debug scripts: debug_*.py, debug_*.rs
- Test scratch files: test_*.c, test_*.rs, test_*.py
- Compiled binaries: debug_parse_simple, test_empty, test_page_class, test_parse_simple, test_pdf, test_classifier_corpus, test_trailer_debug*, test_trailer_key*, test_trailer_parse*, libstdin.rlib
- Backup files: serve.rs.bak, v2.pdf.bak
- tests/fixtures/ compiled binaries and generator drafts: gen_fixtures, gen_ocr_fixtures, gen_suspects*, gen_unmapped_*, generate_suspects_fixture*, generate_suspects_fixtures.py
- Scratch project directories: gen_unmapped_bin/, gen_unmapped_configurable_bin/
Extend .gitignore to prevent future tracking:
- Compiled binaries in repo root and tests/fixtures/
- Debug/scratch files and backup files
- Output files (0, --1.ppm, mod, out.pdf, *.rlib)
Note: Some output files (0, --1.ppm, mod, out.pdf, memory-report.json) were not tracked and are now covered by .gitignore.
Useful generator scripts in tests/fixtures/ (generate_*.py, generate_*.rs) are preserved.
Verification: Repository structure now matches normative file layout from docs/plan/plan.md.
