 * Google Gemini is the one today: chat models always read

 * embeddings, and image generation historically read `GEMINI_API_KEY`. Both
 * names hold the same Google AI Studio key, so every reader accepts either
 * and every writer uses the canonical name. Rows saved under the legacy name
 * keep working; nothing is moved or rewritten.
 *
 * Free of runtime imports so client code and boot-time registrations can use
 * it. The resolvers live in `server/secret-key-aliases.ts`.
