Ruff rule set too narrow — missing I (import sort), B (bugbear), UP (pyupgrade)

[codeforester]

Problem

pyproject.toml:106 configures Ruff with a minimal rule set:

[tool.ruff.lint]
select = ["E4", "E7", "E9", "F"]

This covers only basic pyflakes (F) and a narrow slice of pycodestyle (E4, E7, E9). Missing rule groups that directly affect code quality in a library:

• I (isort) — import sorting. Currently imports in some modules are inconsistently ordered. Enforcing this reduces review noise and keeps files readable.
• B (flake8-bugbear) — catches common bugs: mutable default arguments, loop variable capture, assert misuse, bare except clauses. Especially relevant in a framework where consumers will copy patterns.
• UP (pyupgrade) — enforces idiomatic Python 3.10+ syntax. Since requires-python = ">=3.10", pyupgrade can enforce X | Y unions, match where applicable, and other modern syntax that adopters will copy.

Fix

Expand select to:

[tool.ruff.lint]
select = ["E4", "E7", "E9", "F", "I", "B", "UP"]
ignore = ["E501"]  # keep existing line-length exclusion

Run ruff check --fix lib/python/base_cli/ to auto-fix safe violations before committing. Review B violations manually — some may require logic changes.
