#3054 ("remove 9 dead/unreachable free providers") removed the petals/nanobanana
configs, registry entries and validators but left dangling references that broke
the build and the unit suite on release/v3.8.8:
- open-sse/executors/petals.ts imported the deleted ../config/petals.ts
(webpack "Module not found" → `next build` failed). Removed the executor, its
registration + re-export in executors/index.ts, and the leftover
`providerId === "petals"` branch in providerAllowsOptionalApiKey.
- Removed tests for the now-deleted providers: executor-petals.test.ts and
poolside-provider.test.ts (REGISTRY.poolside was removed), and the petals /
nanobanana validator assertions in provider-validation-specialty.test.ts,
plus the stale petals catalog assertions in providers-page-utils.test.ts,
proxy-connection-test.test.ts and providers-route-managed-catalog.test.ts.
The image/video/embed registries for nanobanana/replicate/nomic are real and
untouched — only the dead chat/api-key surfaces were removed. 146/146 affected
tests pass; typecheck / build clean.
