parser.py and update_mods.py were missing
'from __future__ import annotations', causing a TypeError on
Python < 3.10 when the X | Y union syntax is evaluated at runtime.
All other modules already had the import.
Also lowers MIN_PYTHON from 3.11 to 3.9 -- the toolchain does not
use any Python 3.10/3.11-specific stdlib features beyond the union
annotation syntax which is now handled by the future import.
