ci-tests: guard trigger paths miss .github/workflows/aeon.yml

[aaronjmars]

Follow-up from #1026.

That PR added a pyyaml regression guard measuring the templated Run step in .github/workflows/aeon.yml against the 21000-char GitHub expression limit. But the ci-tests trigger on.pull_request.paths / on.push.paths only list the root aeon.yml (the config file), not .github/workflows/aeon.yml.

Result: a workflow-only edit to the Run block (the exact regression this guards against) will not fire the guard unless the PR also touches scripts/** / bin/** / adapters.

Fix: add .github/workflows/aeon.yml to both path lists in ci-tests.yml.
