ci: add GitHub Actions workflow and dynamic coverage badge generation

- Add .github/workflows/ci.yml with typecheck, lint, build, test, and badge publishing

- Add scripts/coverage-badge.mjs to generate shields.io endpoint JSON from coverage summary

- Update vitest.config.ts with json-summary reporter and include package sources

- Update README.md coverage badge to read from badges branch endpoint

- Ignore badge directory and ignore .next in eslint.config.js
