Add hook 5 (loadModelFromFileAsync), combatlog stub, framecrash vtable hooks, marker assets

Hook 5 intercepts loadModelFromFileAsync (0x71d4e0) to synchronously load M2
model data for fake in-memory file contexts. processLoadedModelData returns 1
and entities are created, but file context cleanup is currently skipped (leaks
0x60 bytes per load) due to a crash in the cleanup path, and there's a later
EIP=0 crash during the game main loop that needs investigation.

Also adds: combatlog module stub, framecrash anchor vtable hooks (GetRelativeTo
and GetWidth/GetHeight crash guards), embedded Raid_UI_FX model assets with
skins and textures, WU_XYZ debug model.
