fix(setup-gbrain): warn about the ZeroEntropy sunset before Sept 4

Browse Source 
ZeroEntropy was acquired by Notion and sunsets its hosted API on September 4, 2026. A gbrain configured with the zeroentropyai embedding recipe keeps importing pages after that date but embedding silently fails — pages land structurally with no semantic search, this repo's tracker P1 (TODOS.md NEXT PRIORITY). Nothing in gstack ever recommended ZeroEntropy (the dependency is gbrain-internal), so the gstack side is detection + advisory: the wireup helper warns when ~/.gbrain/config.json names the recipe (fail-open grep — a missing, unreadable, or other-provider config stays silent and never blocks a working setup), the setup-gbrain provider-default comments say never to select the legacy recipe for a new brain, and USING_GBRAIN_WITH_GSTACK.md gains a troubleshooting entry. The gbrain-side provider migration stays open upstream.
