Fix cull mode + isolate head-collapse to a libgr2 curve bug

Rendering fixes (real):
- m2_material shaders: cull_disabled -> cull_back (inside-of-mesh faces were
  z-winning and darkening/hiding the head under the ShaderMaterial path).
- drop `* COLOR` from the shader (meshes carry no ARRAY_COLOR).

Animation: convert gr2 global poses to Godot *local* bone poses and set via
set_bone_pose (was set_bone_global_pose). MTGODOT_VERIFY=1 confirms
get_bone_global_pose(i) == conv(world[i]) for all 75 bones (<=2.6e-5).

Head/upper-armor collapse on dance_1 is NOT a Godot-route bug:
- reproduced identically in xrender-poc's bgfx demo at the same anim/t
- reproduced by the new MTGODOT_CPUSKIN=1 reference path (same LBS math as
  xrender's validated skin_mesh)
- `general/wait` / `run` render correctly in all three
=> upstream libgr2 Curve::eval (degree-2 quaternion B-spline) vs Granny.
Demo default animation switched to general/wait; documented in MIDREVIEW §4
and README. Debug scaffolding gated behind MTGODOT_VERIFY / MTGODOT_CPUSKIN.

M2.5: ShaderMaterial + texture resolution + fog; multi-skeleton verified

- m2_material: Metin2-style ShaderMaterial. blend_mix shader (opaque /
  alpha-blend / alpha-test-cutout via `mode` uniform) + blend_add shader
  (additive glow). modulate(tex, COORD) * COLOR, diffuse_lambert.
- Metin2Model: material_mode prop ("metin2" ShaderMaterial | "standard");
  _resolve_texture does filename-convention + case-insensitive dir scan of
  *.dds (face/hair keyword slots, stem match, fallback); set_surface_texture
  override; guess_blend heuristic (hair->cutout, cape->alpha, effect->add).
  Texture cache. Fixed opaque path to NOT alpha-discard (was hiding bodies).
- harness: AABB-based camera framing, engine depth fog (MTGODOT_FOG=1),
  MTGODOT_ANIM_T fixed-pose capture (needs explicit anim reload first),
  MTGODOT_AUTOSHOT batch screenshot.

Verified: warrior 5/5 surfaces textured under the shader (t=9 dance pose,
lit, fogged). assassin 17/17 textured via dir scan. shaman_lord (gr2 v7)
renders. Screenshots test/golden/m25-*.png, m2c-t*.png.

Gap (M2.5 gate not closed): libgr2 POD API exposes no material/texture-name/
blend data, so multi-slot -> texture/blend mapping is heuristic only. Needs
a libgr2 material API (gr2_material.cpp walking the type tree) — same gap as
xrender-poc M1 T5. Documented in docs/GODOT-POC-PLAN.md §M2.5 T2.5.6.
