BREAKING CHANGE: removed `baoyu-imagine` and `baoyu-image-cards`. All
functionality now lives under `baoyu-image-gen` and `baoyu-xhs-images`
respectively. Cross-skill `## Image Generation Tools` examples updated
across baoyu-article-illustrator, baoyu-comic, baoyu-cover-image,
baoyu-infographic, and baoyu-slide-deck.
Migration: existing `~/.baoyu-skills/baoyu-imagine/EXTEND.md` configs are
auto-renamed to `…/baoyu-image-gen/EXTEND.md` on first run via the
legacy-path resolver in `scripts/main.ts`.
Add OPENAI_IMAGE_USE_CHAT env var (true|false) to route image generation
through /chat/completions instead of /images/generations. Extracts base64
image data URLs from the chat response, enabling compatibility with
OpenAI-compatible providers that return images via chat API.
- Support --ref with OpenAI GPT Image models (gpt-image-1.5)
- Auto-select Google or OpenAI when --ref provided
- Change ref-related warnings to explicit errors with fix hints
- Add reference image validation before generation
- Improve retry logic to skip non-retryable errors
