zwitschi 286d9f6479 refactor(tools): one FBX export preset instead of six copies

The bpy.ops.export_scene.fbx argument block was duplicated in six scripts (hero,
block frontage, north buildings, site, scale test, MPFB character) and all six
carried mesh_smooth_type="OFF", which drops smoothing groups and made every
Unreal import warn and every round part faceted.

Tools/fbx_export_preset.py now owns the presets:
- preset_kwargs(preset, selection, **overrides) is bpy-free and unit-tested;
- export_static()/export_character() are thin wrappers that import bpy lazily;
- ue_metric_v1 and ue_character_v1 keep the recorded scale contract
  (FBX_SCALE_NONE, apply_unit_scale, -Y forward / Z up) and use FACE smoothing.

Callers switched: hero_facade_build, export_block_frontage, export_north_buildings,
scale_test_export, mpfb_character_export, Art/blender/site/export_site_fbx.

Verified by re-exporting every asset through the preset and re-importing all of
them: 0 smoothing warnings on site, frontage and north buildings; packaging and
-qaselftest all PASS (walk, transect 0 holes, wall probe 0/35, facade probe 0/9).
49 tool tests pass (9 new for the preset contract).

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.
