feat(baoyu-image-gen): add codex-cli provider wrapping codex-imagegen

Expose Codex CLI's built-in image_gen tool through baoyu-image-gen's standard CLI + batch flow as a dedicated provider. The provider spawns the bundled scripts/codex-imagegen/main.ts (synced from packages/baoyu-codex-imagegen/src/) so the skill remains self-contained and inherits retry, cache, file-lock, and JSONL logging. No OPENAI_API_KEY required — uses the user's Codex subscription. New env vars: BAOYU_CODEX_IMAGEGEN_{BIN,CACHE_DIR,TIMEOUT_MS,RETRIES,LOG_FILE}. Hyphenated provider names now resolve under-scored env vars (e.g., BAOYU_IMAGE_GEN_CODEX_CLI_CONCURRENCY). codex-cli is never auto-selected — pin via --provider or default_provider in EXTEND.md.
