 * Image Generation Provider
 * Multi-provider image inference with circuit breakers and cost tracking.

 * Supports:
 *   - Cloudflare Workers AI (SDXL Lightning, FLUX Klein, FLUX Dev)
 *   - Google Gemini (Flash Image, Flash Image Preview)
 *
 * Extracted from img-forge production codebase. Battle-tested.
 *
 * @deprecated Use the img-forge service or the img-forge MCP tools instead.
 * ImageProvider is a frozen snapshot of img-forge's internals and will not
 * track new models or providers. For image generation from within a Worker,
 * call the img-forge gateway via fetch or the GATEWAY service binding.
