Split the sidebar into three parts and rename the add-on CADshot (1.13.0)

Three parts
- A Part switcher at the top of the sidebar picks Clay, Patches or
  Variants; every panel polls on it, so Clay never shows a texture
  control and Patches never shows a camera one
- Top-level panels per part: Clay 8, Patches 6, Variants 11, in
  place of one stack of 18 that showed everything at once
- The part writes through to render_mode, pool_variants and
  pool_patches rather than replacing them, so the renderer, the
  command line, the manifest and provenance need not know parts
  exist; it fires only on a change, so Clay can still be set to
  Full or Both from its own Output panel
- Lighting, the ground and the base material poll on needs_lighting()
  rather than on the part: clay carries Workbench's own studio light
  and the ground is hidden for any non-Full render, so they show only
  when something in the run is lit by the scene
- Products holds the render list, and in Variants each product's own
  material choice, which is what decides whether it takes a draw
- Camera protocols, annotations, drawings, randomization and the
  manifest moved into one collapsed Dataset & research section
- The guide is written per part

Material patches as a part of their own
- Render All plans patch jobs with no product, no camera and no
  stage, so patches gained the progress bar, the time left, Esc,
  Skip Existing and manifest rows the standalone operator lacked
- Texture Size is hidden for patches, which show one repeat filling
  the frame whatever size the real part would be
- part = PATCHES runs from a job file with no inputs at all

Pre-flight
- The Patches part is no longer asked about products, cameras,
  views, naming clashes or lighting
- New error: patches with Workbench as the engine and the Cycles
  add-on off, which used to raise mid-run when the stand-in swap
  to Cycles had nothing to swap to

Rename
- bl_info, the sidebar tab, panel labels, the status bar, console
  prefixes, the manifest's tool field and the citation say CADshot
- The add-on folder, the MV_ collections, the mv. operator names and
  the lighting preset folder keep theirs, so blend files and job
  files written before the rename open unchanged

Documentation
- README: a Three parts section, Workflow reordered to follow the
  panels (Products, Standardize, Views, Stage, Texture Pool,
  Output), troubleshooting for a hidden panel and a missing Stage
  control, and a sentence in Orient Products that had lost its start

Tests
- test_parts.py: the write-through, which panels each part polls in,
  every draw() run through a layout shim, patches rendered with no
  product in the scene, mode-aware pre-flight, and a patches-only
  job file through the command line

-  A Blender add-on that turns CAD (STEP, IGES) and mesh files into standardized
-  multi-view image sets and datasets: canonical camera rigs or published
-  protocols, studio lighting, clay, line-art, depth, normal and part-ID passes,

+  A Blender add-on that turns CAD (STEP, IGES) and mesh files into three kinds of
+  standardized image set: multiple clay views of a product's form, patches of the
+  materials in a texture pool, and products rendered across every combination of
+  view and texture. Canonical camera rigs or published protocols, studio lighting,
+  clay, line-art, depth, normal and part-ID passes, camera poses, COCO and BOP
+  annotations, vector engineering drawings, seeded randomization, and a provenance
+  manifest with Croissant metadata. Formerly MultiView Product Renderer.
