Authoring stage — bake lighting, AO, normals, and custom maps from

# maya-texture-bake (Authoring stage)
Bake lighting / AO / normals / custom shading networks to image
textures via Maya's bundled bake workflow. All four scripts are
main-thread-affine and CPU-heavy — set realistic `timeout_hint_secs`
in `tools.yaml`.
## Scripts
+ - `bake_textures` — Sample a mesh's unlit material `baseColor`/`color` network
+ into non-empty IFF UV textures using Maya `convertSolidTx`. Each object must
+ have one mesh shape, one shading group and one surface material; ambiguous
+ assignments fail. `bake_type="diffuse"` means base-color sampling, not an
+ Arnold diffuse lighting pass. Arnold RTT, full-render, normals, AO and UDIM
+ baking are not implemented by this tool. The legacy `renderer="arnold"`
+ argument is retained, but results identify `backend="maya.convertSolidTx"`.
+ Renderer and selection are restored; partial failures retain verified files
+ and report per-object errors. `overscan` is retained but unused.
- `bake_lighting` — Bake full lighting (diffuse + shadows) to a texture via `convertLightmap`
- `bake_ambient_occlusion` — Bake AO using a `mib_amb_occlusion` shader
- `transfer_maps` — Transfer normals/displacement/diffuse from high-res to low-res mesh
- `list_bake_sets` — List existing bake set nodes in the scene
