/**
 * Stability AI Provider — direct image generation.
 *
 * Hits api.stability.ai/v2beta/stable-image/generate/{model}. Returns
 * base64 PNG. No chat / streaming / tool calling.
 *
 * The constructor no longer throws when `STABILITY_API_KEY` is absent so
 * that per-call credentials (passed via `options.credentials.stability`) can
 * be used without requiring a global env var at startup.
 *
 * @see https://platform.stability.ai/docs/api-reference
