Adopt C4

:point_right: [ZeroMQ's C4 Process](http://rfc.zeromq.org/spec:22), a collaboration model for free software projects that focuses on community success and shared ownership.

What needs to be done before we can say that we follow C4:
- [ ] Pre-commit hooks to run `go fmt` for Go, and `eslint` for JS code
- [ ] Add automated tests + CI integration

Start by locating the project’s pre-commit configuration, Go and JavaScript source, existing tests, and CI configuration. Verify that pre-commit runs go fmt and eslint, then add automated tests and CI integration. Done means both checklist items are implemented and the project follows the referenced C4 process.
