Summary

The Pytest (All, Python <ver>, Ubuntu) matrix has been failing on main since ubuntu-latest moved to ubuntu-26.04. Each version has about 210 failures, and Pytest (All, Python 3.10, Ubuntu) is a required check, so this blocks every PR.

• fd9e6c22 (Oct 30) ran on ubuntu-24.04, and the 3.10 job passed.
• d2b0ae5e (Nov 3, current main HEAD) ran on ubuntu-26.04, and the 3.10 job failed (210 failed, 6077 passed).
• On 26.04, the tracebacks in the "Python 3.10" job point into /usr/lib/python3.14/asyncio/events.py (RuntimeError: There is no current event loop). So the tests are running under the system Python 3.14 rather than the matrix version. I haven't pinned down the exact mechanism; the venv is still named ...-py3.10.

-    runs-on: "${{ matrix.os }}-latest"
+    runs-on: "${{ matrix.os }}-24.04"

The matrix job names are unchanged, so the required-check contexts still match.

Follow-up

• Find the actual interpreter-selection issue on 26.04, for example by having Poetry use the setup-python interpreter explicitly. Then remove this pin.

Requested by Oleksandr Bazarnov (Baz (@bazarnov)) in Slack, to unblock #1260.
