ci(workflows): align workflows with package.json scripts

- Replace npx tsc --noEmit with npm run type-check for consistency
- Remove tests-validate job, tests now run via vitest (test:ci)
- Add test job running npm run test:ci
- Replace node scripts/fetch-github-stars.mjs with npm run fetch:github-stars
