… 3.10 wheels The oldest-requirements CI leg pins pyzmq to its declared minimum. pyzmq 22.0.0 ships no wheels for Python 3.10+, so it is built from source, and its bundled libzmq fails to compile against GCC 13's libstdc++ on ubuntu-24.04 (static assertion in allocator_traits for secure_allocator_t). 22.2.1 is the first pyzmq release with cp310 wheels for Linux, macOS and Windows, so it is the lowest version installable on LitServe's minimum supported Python without a compiler.

What does this PR do?
Moves the remaining floating and retiring runner labels to pinned images, and aligns everything on
ubuntu-24.04,macos-26,windows-2025(ci-testing.ymlalready hadwindows-2025).ci-checks.yml:ubuntu-latest/macos-latest/windows-latest→ubuntu-24.04/macos-26/windows-2025ci-testing.yml:macos-15→macos-26, and the "oldest requirements" leg moves fromubuntu-22.04toubuntu-24.04. Since that leg now shares an OS with the base matrix,requires: ["latest"]is added to the base matrix so it stays a separate job instead of replacing the 3.10 "latest" run (same pattern asLightning-AI/utilities). Job count is unchanged (12 + 1).pyproject.toml:pyzmq>=22.0.0→>=22.2.1. The oldest-requirements leg pins the floor, and 22.0.0 has no Python 3.10 wheels, so on 24.04 it builds from source and fails with GCC 13. 22.2.1 is the first release with cp310 wheels.Why
