- Add `_PyTag` helper class to `wheel_tag.py` to make the
  complex `all()` ABI tag checks readable; refactor `compute_best`
  to use it
- Restructure the `limited_api` block in `builder.py`: move the
  `cp3*t` branch inside the `cp3` check, add a warning when the
  free-threaded stable ABI is requested but conditions aren't met,
  and move the classic-on-free-threaded warning into the inner branch
- Promote the inline `VersionInfo` test helper to module level in
  `tests/test_builder.py` and add a `from_str()` classmethod
