Register the Claude Code x Fable 5 Max combination as its own entry

The minecraft.html artifact is Fable 5 Max run inside Claude Code — a
different harness from the existing Claude Web App entry, so per the
model x harness x effort architecture it becomes a new combination
(claude-fable-5-code) rather than a variant. The validator now also
rejects loose files under outputs/<id>/ that no run declares, which is
how this artifact briefly slipped into the repo unregistered. OG count
refreshed (11 -> 12 ran).
