v2.2.0

Features

• baoyu-image-gen: new codex-cli provider that wraps the codex-imagegen backend so the Codex image_gen tool is reachable through the standard --provider / batch / EXTEND.md flow. Uses the user's Codex subscription — no OPENAI_API_KEY required. Adds env vars BAOYU_CODEX_IMAGEGEN_{BIN,CACHE_DIR,TIMEOUT_MS,RETRIES,LOG_FILE} and resolves hyphenated provider names for BAOYU_IMAGE_GEN_<PROVIDER>_* overrides (e.g., BAOYU_IMAGE_GEN_CODEX_CLI_CONCURRENCY). codex-cli is never auto-selected — pin via --provider codex-cli or default_provider: codex-cli in EXTEND.md

Refactor

• codex-imagegen: extracted from scripts/codex-imagegen/ + scripts/codex-imagegen.sh to its own workspace package at packages/baoyu-codex-imagegen/. The bash shim is gone; src/main.ts now carries a #!/usr/bin/env bun shebang and is the sole entrypoint (bun packages/baoyu-codex-imagegen/src/main.ts … or, without bun on PATH, npx -y bun …). scripts/sync-codex-imagegen.sh keeps skills/baoyu-image-gen/scripts/codex-imagegen/ in sync for skill self-containment

Documentation

• baoyu-cover-image: replace the long inline scripts/codex-imagegen.sh invocation block in SKILL.md with a pointer to references/codex-imagegen.md, documenting the preferred baoyu-image-gen --provider codex-cli path and keeping the direct-wrapper fallback
• baoyu-article-illustrator, baoyu-comic, baoyu-infographic, baoyu-slide-deck, baoyu-xhs-images: add a Codex via codex exec branch to each skill's backend-selection ladder and ship a per-skill references/codex-imagegen.md with the invocation contract (preferred path, fallback, stdout schema, batch semantics)
• docs/codex-imagegen-backend.md and CLAUDE.md: update path layout and invocation examples to reflect the new workspace package location
