Use the standalone Ruff section name

When this file is auto-discovered by ruff check . or passed as --config ruff.toml, Ruff treats ruff.toml as rooted at Ruff settings rather than the pyproject.toml [tool.ruff] namespace. This table makes the entire committed config fail to load with unknown field tool, so Ruff lint/format checks cannot run for the repo until it is renamed to [lint.per-file-ignores].
