ci: reduce runner sizes on various jobs
These jobs can use reduced runner size to avoid wasting CPU, as much of
the long-running part of the job is single-threaded.
Suggested in: https://github.com/bitcoin/bitcoin/pull/32989#discussion_r2321775620

What changed, and why it matters
This commit only changes the sizes of virtual machines used by Bitcoin Core's automated testing pipeline on GitHub. It switches several jobs from medium/large runners to smaller ones to save computing resources. There is no change to the Bitcoin software itself, no user-facing change, and no security relevance.
No action needed. This is a benign CI configuration change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies .github/workflows/ci.yml, downgrading Cirrus runner labels from -md/-lg to -sm/-md and the lint job from -sm to -xs. This is a CI infrastructure cost/efficiency optimization. No source code, build scripts, dependencies, or runtime behavior of Bitcoin Core is affected.
