cjkas 99c6019431 feat: web UI protocol 2 client layer, JS and CSS bundles (step 2a)
- data-src/js: ProtoSchema (schema from the sync, short keys and names,
  defaults, cached by hash), ProtoModel (rooms, shades, groups, repeaters,
  header and status from the sync and the events) and ProtoClient (/ws,
  hello, sync with next, op() as a Promise of its reply, events, feeds,
  reconnect). Nothing uses them yet: 2b moves the UI onto them.
- minify.py joins js/*.js and index.js into index.js, and the three CSS
  files into app.css, so a page load opens fewer connections.
- test/js: node --test on the three modules, replaying the recorded
  fixtures; a CI job runs it and the firmware build waits for it.
