🔧 Consolidate code formatting tools into Ruff configuration

Removes separate Black and isort configurations in favor of Ruff's
built-in formatting and import sorting. Standardizes line length to 88
chars and adds per-file linting rules for tests. Simplifies toolchain
while maintaining code quality standards.
