engine(windows-x64): publish 2caca361 — b1bc0aef + get_video_adapter_memory

Windows editor built from tinqs/engine 2caca361 on UyGar's machine (2026-10-03),
the build ariki-game's settings/hardware lane has been running on. --version
prints 4.7.2.stable.mono.custom_build.2caca3619; d3d12, angle and accesskit
confirmed present in the binary.

GodotSharp regenerated from this binary (glue has Terrain3D +
GetVideoAdapterMemory) and replaced wholesale: nupkgs are 4.7.2 only (the game
pins Godot.NET.Sdk/4.7.2), and the stray nested GodotSharp/GodotSharp copy is
gone (the Mac layout never had it).

Not included: the 2026-10-05 round (shadow pass diet, staggered/fit cascades,
shadow_lod_bias, GPU MultiMesh cull Stage A/B). ariki-game guards each of those
(HasMethod checks, ProjectSettings no-ops), so the game runs; those knobs just
do nothing on Windows until a build from main.
