chore(brand): resync the model counts from the published artifact

blockrun#734 retired a chat SKU, so the catalog has been 77 chat / 104 total
since. The weekly brand-sync workflow would have carried that here by itself,
except GitHub Actions is failing in 2s with zero steps org-wide — a billing
stop — so it has not run. This is `sync-brand-numbers.mjs --refresh` by hand.

`--check` reports "up to date" throughout, correctly: it never touches the
network and compares markers against the committed brand-numbers.json, which
was itself stale. Only --refresh can see drift of this kind.
