Subject: [PATCH] ci: revert ASAN runner to ubuntu-latest (r-hub gcc-asan has
 no arm64 image)

The 2026-06-19 ubuntu-latest->ubuntu-24.04-arm switch (01c99be9) broke
the workflow: the ghcr.io/r-hub/containers/gcc-asan image has no arm64
variant, so the container dies at init (~35s, 'container is not
running') before any ASAN work. Revert to the ubuntu-latest (x86)
config that ran green for 42 min on 2026-06-16 (decfe3e9).
