fix(ci): key Python environment caches by resolved interpreter version

[m1so]

Runner image updates can restore virtual environments created with a different Python patch version, causing Poetry to recreate the environment and unit tests to fail with Command not found: pytest.

Key CI and CD environment caches by the resolved Python version, OS, and architecture. Dependency installation continues to be skipped on cache hits.

Validation: both workflow YAML files parse, cache step references checked, and git diff --check passed.

Summary by CodeRabbit

• Chores
  • Updated dependency caching in automated checks and release workflows to account for the operating system, processor architecture, and Python version. Pull-request checks also distinguish dependencies by their source repository.
  • These workflow updates do not change app features or behavior.

📝 Walkthrough

Walkthrough

CI and publishing workflow cache keys now include runner OS and architecture. Several CI keys use the Python version reported by setup-python. The mypy and unit-test setup steps now have IDs so their outputs can be referenced in those keys.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~4 minutes

Change: Bug fix

Suggested reviewers: mfranczel

Merge Risk: ⚪ Minimal · up to 4707e

The reviewed cache keys distinguish resolved Python versions where cached environments are reused, so no merge-blocking cache risk was identified.
