refactor(codex-imagegen): extract backend to packages/baoyu-codex-imagegen workspace

Move the codex-imagegen wrapper out of scripts/ into its own workspace package alongside baoyu-md, baoyu-chrome-cdp, and baoyu-fetch. Drop the bash shim — src/main.ts now carries a `#\!/usr/bin/env bun` shebang and serves as the sole entrypoint. Add scripts/sync-codex-imagegen.sh so skills/baoyu-image-gen/scripts/codex-imagegen/ can be regenerated from packages/baoyu-codex-imagegen/src/ for skill self-containment. Update CLAUDE.md, docs/codex-imagegen-backend.md, and the CI workflow paths accordingly.
