fix: repair a11y CI workflow after game.js removal (closes #100)

PR #92 removed game.js but the a11y workflow still grep'd and
syntax-checked it. Rewrote to validate the current file layout:
- aria-label/aria-pressed across js/*.js
- role= and aria-label in index.html
- node -c syntax check on all js/*.js files

smoke.yml was already clean — no changes needed.
