chore: consolidate Ruff configs, add prettier dependancy and updated documentation usage

- Remove per-package Black, Ruff, and MyPy settings in individual pyproject.toml files
- Centralize Ruff configuration in root pyproject.toml under [tool.ruff.lint] with selected ignores
- Add Prettier setup and usage instructions to Development.md
- Include pnpm install instructions for JS/TS dependencies
- Ensure pre-commit hooks enforce Python and JS/TS formatting consistently
