Jim Liu 宝玉 c3cbce9ce3 feat\!: rename baoyu-imagine→baoyu-image-gen, baoyu-image-cards→baoyu-xhs-images (v2.0.0)
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`.

# Codex Image2 Fallback
When using `baoyu-image-gen` with `--provider openai --model gpt-image-2`, the CLI can fail with:
```text
OPENAI_API_KEY is required. Codex/ChatGPT desktop login does not automatically grant OpenAI Images API access to this script.
```
This is expected. The `openai` provider uses the public OpenAI Images API and needs `OPENAI_API_KEY`. Codex / ChatGPT image2 entitlement is a separate runtime-native path.
## Practical fallback pattern
1. Try `baoyu-image-gen` when provider credentials are available.
2. If it fails only because `OPENAI_API_KEY` is missing, do not leave the user waiting.
3. Prefer a Codex/native raster backend in this order:
- Codex runtime native `imagegen` skill/tool, if available.
- Repo-level `scripts/codex-imagegen.sh`, if `codex` CLI is installed/logged in and the calling skill supports the wrapper.
- Hermes native `image_generate`, if available.
4. Be transparent about reference-image behavior:
- If the fallback backend accepts references, pass the reference images.
- If it does not, derive a concise identity-preserving prompt from the references and state that it is a text-description fallback, not strict reference-image editing.
5. Return the generated media path or structured backend error promptly.
## User-facing wording
Use concise wording such as:
> The OpenAI API path needs `OPENAI_API_KEY`; Codex login is a separate image2 backend. I used the available Codex/native image backend instead. Reference images were [passed directly / reconstructed from visual traits].
Avoid implying that `baoyu-image-gen --provider openai` can use Codex OAuth without a dedicated provider implementation.
