fix: revert Python 3.10 CI matrix expansion (#323)

Reverts commit 9c8ee2c which broke CI — the validation scripts use
tomllib (Python 3.11+) but ran under bare python3 on the 3.10 matrix.
The PR auto-merged despite failing gates, which is a separate branch
protection bug.

This reverts commit 9c8ee2c.
