ci: split pipeline into two independent tracks (Node + Go)

- build-node depends only on node-test
- build-go depends only on go-test
- deploy-node depends only on build-node
- deploy-go depends only on build-go
- publish job waits for both deploy-node and deploy-go to complete
- Badges and deployment summary moved to final publish step

Result: Go staging no longer waits for Node tests to complete.
