- Add __clib4_resource field to struct _clib4 for caching the global resource pointer
- Initialize cache once in stdlib_memory_init instead of calling OpenResource() on every allocation
- Update __get_wmem_allocator, __memory_lock, and __memory_unlock to use cached pointer
- Eliminates 3 OpenResource() calls per malloc/free (hot path optimization)
- Maintains global allocator semantics and thread-safety through shared resource semaphore
