⬆️ Modernize pre-commit config with Ruff and Prettier

Consolidates Python tooling by replacing Black, isort, and Fixit
with Ruff for faster linting and formatting. Adds Prettier for
consistent formatting of JS/JSON/YAML/Markdown files. Updates hook
versions and adds descriptive names for better developer experience.
