Subject: [PATCH] ci: test all 4 Python versions on PRs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Run 3.10, 3.11, 3.12, 3.13 on every PR — we need to catch
version-specific breakage before merge. Removes the configure
job since the matrix is now static. Still 16 jobs (4×4) vs 32.
