Point children at Ox Alpha, by its real slug

The preference list reached `opencode/big-pickle`, which is a different model.
Ox Alpha is `opencode/x-preview-f-free`, and nothing about that name says so:
searching the harness's 101 models for "ox" or "alpha" finds nothing at all,
which is exactly how the first pass at this list picked the wrong one.

The slug is confirmed twice. opencode's own normalization maps `x-preview-f` to
`ox-alpha` in `packages/stats/core/src/domain/model-normalization.ts`, and the
`-free` entry is the unlimited tier its picker shows as "Ox Alpha Free
(Unlimited)" under OpenCode Zen. Then it was run: a child on that model answers,
and a two-child fan-out on the default answers too, 25.7k tokens each, no grant
anywhere.

So the priority asked for now holds as asked: Ox Alpha first, Gemini behind it,
both free, neither minting anything. The grant path remains only as the fallback
for a machine whose harness lists none of them.

416 tests pass.
