release 0.8.2

Added (#39)

• retexture create --ai-model latest|meshy-7|meshy-6|meshy-n1. Meshy N1 (meshy-n1, 10 credits) makes a 2K base color texture from reference images only: one --image-style-url, read as the front view, or 1–4 --multiview-image-urls, front first and the rest in any order.
  • With N1 the defaults follow the model: enable_pbr: false and texture_resolution: "2k", and multi-view is not pinned to meshy-7. This holds whether N1 comes from the flag or from --data. Every other model keeps PBR on, 4k, and the meshy-7 pin on multi-view.
  • With N1, these are refused before the create (exit 2), by flag or by --data: a text prompt, enable_pbr: true, 4k/8k, hd_texture: true, remove_lighting, and a request with no reference image. Two of them are stricter than the API on purpose: a prompt beside one image (the API drops it) and hd_texture: true beside an explicit 2k (the API runs at 2k).
  • --ai-model latest|meshy-6 with --multiview-image-urls is refused locally.
  • The face limit is the API's; meshy inspect faces --model measures a local GLB.
• Docs: D-090 in docs/decisions.md, docs/usage.md, and the skill.
