feat: migrate linting/formatting from flake8 + isort + yapf to Ruff #1743

• I have marked all applicable categories:
  • documentation request
  • new feature request
• I have visited the [source website], and in particular read the [known issues]
• I have searched through the [issue tracker] for duplicates
• I have mentioned version numbers, operating system and environment, where applicable (not relevant for a tooling change)

Would the maintainers be open to migrating the linting and formatting toolchain from flake8/isort/yapf to Ruff?

The migration scope is well-defined:

• Replace [tool.flake8], [tool.isort], and [tool.yapf] in pyproject.toml with a single [tool.ruff] section
• Replace the flake8 + isort pre-commit hooks with a single Ruff hook
• All flake8 plugins currently in use (bugbear, comprehensions, isort, and pyupgrade equivalents via UP rules) have direct Ruff implementations
• yapf's column_limit = 99 and other style settings map cleanly to Ruff's formatter config
• pyupgrade could either be kept as-is or absorbed into Ruff's UP ruleset — happy to defer to maintainer preference

The net result would be ~7 tools/plugins consolidated into one, faster CI, and a simpler pre-commit config — with no change to the rules enforced.

Happy to submit a PR if this direction is welcome. Just wanted to check alignment first.
