Pass the pre-build NPC review gate

- Add a review harness that stages all eight library characters at portrait, conversation and crowd distance on both maps in day and night.
- Fix the final-context lanyard badge and firefighter helmet fit with runtime attach offsets; the asset-space gear contract is unchanged.
- Record the gate sign-off, refresh the gallery, and move the completed review to DONE.
