chore: bump minimum Python version to 3.12

- Update requires-python to >=3.12
- Update CI matrix to test Python 3.12 and 3.13
- Update pyright pythonVersion to 3.12
- Remove Python 3.10 and 3.11 from classifiers

Python 3.12+ provides consistent enum string representation
and modern language features used throughout the codebase.
