chore(skills): asset/tooling skills sweep — atlas/glb-gen/image-gen/audio-gen/sprite-gen/bug-report/ticket (T-1103)

Live-command corrections (atlas corridor-status, real body-ID naming), failure-proofed glb-gen/sprite-gen render scripts, Trellis API reference extracted. image-gen: fixed the output-path bug and de-forked the local image_connector.py to the canonical tooling/db/ copy. ticket skill consolidated to point at ticket-cli.md (setparent-none fix applied there too). Part of T-1099.
