chore: remove Black/isort config, update ruff to 0.14.6

- Remove black and isort from dev dependencies (ruff replaces both)
- Update ruff version constraint to >=0.14.6
- Remove [tool.black], [tool.isort], [tool.ruff] sections from pyproject.toml
  (configuration now lives in ruff.toml)
- Add deferred rules to extend-ignore for issues requiring larger refactoring
