Pull request overview

This PR switches the repo’s formatting/lint workflow from Black to Ruff, adds Ruff configuration to pyproject.toml, and applies formatting/type-hint modernization across the codebase (built-in generics, collections.abc imports, and minor style cleanups).

Changes:

• Replace the black tox environment with a ruff tox environment and add Ruff to dev dependencies.
• Add [tool.ruff] configuration (lint + formatter settings) in pyproject.toml.
• Apply repo-wide formatting and typing updates (e.g., Dict → dict, List → list, typing.Sequence → collections.abc.Sequence), plus minor test/sample formatting.
