M0' scaffold: Godot 4.7 + GDExtension + libgr2 wired up (macOS)
- extension/: godot-cpp submodule (master, API 4.7), Metin2Model node registered, links xrender-poc/libgr2 via sibling-dir reference. - project/: Godot 4.7 project — orbit camera + DirectionalLight3D (shadows) + WorldEnvironment/procedural sky + placeholder cube; main.gd probes the extension and can run libgr2 on a real .gr2 (MTGODOT_PROBE_GR2). - build.sh one-shot build into project/bin/. - docs/GODOT-POC-PLAN.md (phased: Phase 1 macOS -> M0'/M1/M2/M2.5). Verified on this machine: [mtgodot] Metin2Model registered OK — libgr2 linked probe_gr2(warrior_cheongrin.gr2) -> gr2 OK: format_version=6 sections=8 Metal Forward+ renders the scene (test/golden/m0-scaffold.png).
