- Split GitHub workflow job actions into multiple jobs

  - lint: Code formatting and style checks
  - test: Unit tests and coverage
  - package: Verifies package can be built
- Add dependencies between jobs:
  - lint -> test
- Add matrix Python version to job names
- Improve caching by creating cache keys for different Python versions
