Subject: [PATCH] Update minimum Python version to 3.10

Python 3.9 reaches end-of-life October 2025. Python 3.10 adoption is
now mainstream - major frameworks (strawberry, Django 5.0, FastAPI) require it.

This enables modern Python features:
- Dataclasses with `kw_only`
- Union types with `|` syntax (PEP 604)
- isinstance() with union types directly
- match statements for pattern matching
