fix(ci): Repair a11y workflow after game.js removal (#100)

The a11y.yml workflow referenced game.js which was removed in PR #92.
Updated to validate the current file layout:

- ARIA attributes: scan all js/*.js files (not single game.js)
- ARIA roles: index.html (unchanged)
- Syntax check: all js/*.js files with node -c

Fixes #100
