+work out script running UX
+- stderr
+- report proper exit code
+- individual control of each pane/task
+work out build dependencies
+- e.g. runner waits on reporter
+- any other examples? if not, just deal with runner/reporter
+wire up interdependencies correctly
+- @cypress/core-runner -> core-runner
+handle deployment
+core-app -> core-server
+more some core-app stuff into root
+tests?
+- unit/integration in each package
+- e2e should be in root
+running all tests
+- needs to be sequential?
+- unit tests in parallel?
+- how are errors reporter?
