…locateVirtualMemory hook Replace the NtAllocateVirtualMemory hook approach with a custom slab-style allocator that manages memory from a pre-reserved block, using size classes and free lists for efficient allocation. The allocator is injected directly into luaL_newstate via code patching. Also add proper Exit() cleanup and move Init() earlier in the startup sequence. Co-Authored-By: GPT5.5

This PR replaces LuaJIT's builtin allocator with custom slab allocator on reserved space, and triggers LuaJIT GC when allocation failed.
Fixes crash on some systems when game calls
lua_newuserdata, reserving 256M is enough, but defaulting to 512M for better stability.Tested for hours with omnimix without crashing
