ux support for receiving test results in realtime from a local testrun and/or triggering new runs

[RonnyPfannschmidt]

in response to #479 (comment)

i'd like to be able to "live-stream testr run results into a browser vi as i run them locally, optionally triggering pytest reruns on changes

this would essentially be something like looponfail, just in the browser

this would require a local webserver to serve the assets + event stream websockets with test results

this would be a consideration for strictly after the new fe/be have landed with feature parity

Would you mind elaborating on the second part? 🤔
