Explicitly set `select` rules to maintain compatibility with
Ruff 0.15.1. Ensures deterministic linting behavior despite changes in
Ruff 0.15.2 defaults.
See https://github.com/astral-sh/ruff/releases/tag/0.15.2 for more
details.
Adopt Ruff `RET` to improve return-flow consistency across the codebase.
Simplify control flow by removing redundant `else` blocks after
`return`, and add explicit `return None` (or equivalent) fallbacks
where appropriate to preserve existing behavior.
Fixes#21411
Update `ruff.toml` with additional exclusions, linting rules, and
formatting preferences. Includes support for respecting `.gitignore`
and a consistent coding style.
