- Add GitHub Actions CI with parallel Go (build/test -race/vet) and Web UI (pnpm build) jobs
- Add Makefile targets: test, vet, check-web, setup, ci
- Fix data race in typing keepalive: remove nil assignment after close(keepaliveDone)
so the goroutine can safely read the channel without holding the mutex
