test(build): add make watchdog, the glance memory budget and the glance screenshot

- make watchdog (in make ci): a stress build encodes, packs, turns into
  runs and draws the largest code of every 2D symbology at two steps per
  event on the Forerunner 255S and 70; it fails on a watchdog trip, and
  the last code left on the screen must decode (bitmap path on the 70).
- make memtest checks the glance (DIAG glance, budget 70 % of 64 KB).
- screenshots.sh launches the app again after the flow and compares the
  glance with the favourite's code (glance_code.png on 7 watches); the
  About goldens show 0.8.0.
