Stop Codex from satisfying a request by copying an unrelated pre-existing
image from generated_images instead of generating a new one. Verification
now requires a PNG in this thread's generated_images dir (or an image_gen
stream item, kept as a forward-compatible signal), and the spawned-agent
instruction forbids reading or reusing history images before image_gen is
called. Removes the findCpToTarget fallback that allowed the shortcut.
Validated against a real codex exec run: image_gen leaves no stream item,
so the filesystem check is the load-bearing signal; locked in via a
condensed real-stream regression fixture.
Closes#185
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.
