A set whose every ROM is NO_DUMP or ROM_OPTIONAL only warns in
handle_missing_file, so the machine runs without it. The parser now
keeps undumped and optional ROMs for that decision, the merge and the
release profiles write required false for such sets, and the text
patcher rewrites the required line it used to leave. A curated false
over a set with dumped ROMs is kept, except over no contents, which is
what an undumped set leaves once a later release dumps it.
pSxMAME builds mamedev/mame itself at 0.133 and left the current
refresh, which would have moved it onto 0.289 refs. Release profiles
keep their citations double-quoted on regeneration.
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).
