Run ruff check --fix: remove unused imports (F401), fix f-strings
without placeholders (F541), remove unused variables (F841), fix
duplicate dict key (F601).
Run isort --profile black: normalize import ordering across all files.
Run ruff format: apply consistent formatting (black-compatible) to
all 58 Python files.
3 intentional E402 remain (imports after require_yaml() must execute
after yaml is available).
Add many MAME/MESS BIOS entries (TRS-80 family, Bandai RX-78, Sega AI) and update docs/navigation counts (README, mkdocs). Remove empty supplemental file references from database.json and update generated timestamps and totals. Harden and refactor tooling: add MAX_RESPONSE_SIZE limited reader in base_scraper, make target scrapers an abstract base, narrow exception handling in the Batocera targets parser, and switch generate_pack.py and verify.py to use build_target_cores_cache (simplifies target config loading and error handling). verify.py also loads supplemental cross-reference names and accepts them through verify_platform. Update tests to import from updated modules (validation/truth). Misc: small bugfix for case-insensitive path conflict check.
