Some ruff / pyright rules to make sure AI write quality code

preview = true
select = [
  "E",    # pycodestyle — hard PEP 8 violations (indentation, spacing, etc.).
  "W",    # pycodestyle warnings — softer style nits you still want fixed.
  "F",    # pyflakes — real code errors: undefined names, unused vars & imports.
  "I",    # isort — keep your import blocks deterministically sorted/grouped.
  "B",    # bugbear — likely bugs and nasty edge-cases (mutable defaults, etc.).
  "C4",   # comprehensions — suggest faster/cleaner list- & dict-comps.
  "UP",   # pyupgrade — auto-rewrite code to the newest-supported Python syntax.
  "C901", # mccabe — flag functions whose cyclomatic complexity balloons.
  "SIM",  # simplify — call out over-engineered constructs; prefer the obvious one-liner.
  "N",    # pep8-naming — enforce PEP 8 names for classes, funcs, vars, etc.
  "RUF",  # Ruff-native extras — Ruff-only correctness/perf rules (a la "unicorn").
  "FAST", # fastapi — idiomatic FastAPI patterns and anti-pattern detection.
  "DOC",  # pydoclint — Google/Numpy docstring section order & completeness.
  "D",    # pydocstyle — PEP 257 docstring formatting conformance.
  "ARG",  # unused-arguments — catch never-used *args/**kwargs/params.
  "PERF", # perflint — flag obvious performance foot-guns (e.g., `list()` in loops).
