ci: split tests workflow into separate ruff, mypy, and pytest workflows

- Create individual workflow files for ruff, mypy, and pytest
- Each workflow has its own status badge for independent monitoring
- Ruff badge shows code quality status
- Mypy badge shows type checking status
- Pytest badge shows multi-version testing status
- Update README with all three badges and clear status documentation
- Remove combined tests.yml in favor of granular workflows
