zwitschi 600633cd5b fix(materials): stop orphaning references; add a scene audit gate

The blockout cleaning pass found the map was rendering with 604 of 620 mesh actors
unmaterialed - every kit piece and all theatre trim.

Cause: ensure_material() deleted and recreated each /Game/Hollywood/Site/M_* asset on
every run, so actors staged by other tools kept references to deleted assets and fell
back to the default material. Nothing errored; the map looked merely slightly flat.

- Materials are now updated IN PLACE (load, delete_all_material_expressions, rebuild
  the graph, recompile, save). Material.expressions is protected from Python, so the
  editing library's deleter is used.
- 53 duplicated kit actor labels fixed (both shop piers of a bay shared one name).
- New Tools/ue_audit_scene.py gates the scene: every mesh actor has a material, every
  verified frontage span is within +/-1 m (via ue_placement), no duplicate labels.
- render_screenshots.sh now runs the chain in the required order (demo map -> kit ->
  theatre -> audit -> cameras -> capture) and exits non-zero on an audit failure,
  because the demo builder rebuilds materials and later staging must follow it.

Scene audit: 0 failures. Packaged QA PASS. Spawn-view reference score 0.72.

Game

The Unreal project lives at Game/GigLine/GigLine.uproject once created. Nothing here yet.

What gets committed

Config/ — engine and project settings, including the quality presets used for release checks
Source/ — C++ modules
Content/ — 0.1.0 map, materials, meshes; LFS-tracked
GigLine.uproject

What does not

Binaries/, Intermediate/, Saved/, DerivedDataCache/ — all generated. .gitignore covers them; do not add exceptions.

Engine

Installed outside the repository. Its path and exact version are recorded in ../Docs/toolchain.md. Nothing in this directory may assume a machine-specific engine path; the documented build procedure is ../Docs/build.md.
