Summary: - Enable the OpenAI image provider from standard OpenAI server env vars when image-specific env vars are absent. - Add provider-config coverage for resolving the fallback API key and base URL. Rationale: - Allows gpt-image-2 image generation to work with common OpenAI proxy configuration. Tests: - pnpm vitest run tests/media/openai-image-adapter.test.ts tests/server/provider-config.test.ts - pnpm prettier lib/server/provider-config.ts tests/server/provider-config.test.ts --check - pnpm lint -- lib/server/provider-config.ts tests/server/provider-config.test.ts Co-authored-by: Codex <codex@openai.com>
