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.

-# Forge (Windows) — rebuild pair from engine main ≥ 615e852f, re-judge the render verdicts, pin (2026-10-05)

-macOS pair `615e852f` (code `c76f2ecc`) is published here. Windows is still `b1bc0aef` (2026-09-28).

-1. Build the Windows editor + console pair from `tinqs/engine` main with the `windows-x64` manifest flags
-   (`platform=windows target=editor arch=x86_64 module_mono_enabled=yes d3d12=yes angle=yes accesskit=yes`),
-   regenerate GodotSharp from that exact binary, smoke (0 wrapper errors), publish here, update `manifest.json` +
-   `README.md`.
-2. Then pin `tinqs/required_engine_build="4.7.2@<hash7+>"` in `ariki-game/project.godot` (both platforms on the same commit).
-3. Re-judge on Windows what the Mac measured (frame GPU-bound on M1): static shadow cache default (now OFF on Apple
-   silicon game-side, ON elsewhere — keep ON on Windows only if `inverted` ≥ `cache_off` fps), GPU veg bands, HLOD.
-   Full recipe + numbers: `ariki-game/.agents/handoffs/2026-10-05-forge-windows-render-bench-handover.md`.
