feat(builder): repair existing templates, a weekly check that queues repairs, and eval

The builder could only create games; nothing noticed when a live template
stopped working, and there was no way to tell whether a builder change made
it better or worse.

- repair -id ID: boots an existing template as nodes run it; if it fails,
  the same investigation as for a draft runs and the model changes only what
  the diagnosis says. The worker handles "repair" jobs (gameId from the
  panel) and opens "fix(games): repair ..." on draft/<id>; a template that
  boots as it is reports "nothing to repair" and opens no PR. The boot and
  fix loop is now shared by builds and repairs.
- validate.yml runs weekly and boot-tests every game; failed games are sent
  to the panel (X-GBR-Event: games_boot_failed) to queue repairs.
- eval -ids all: builds games that already have a template from scratch,
  blind, and scores each draft against it (boots, same image and app, ports,
  ready line, settings found) into eval.md and eval.json.
- research skips our own sites, so neither research nor eval reads our
  templates back.
