gguf : reject tensor size that wraps after padding (#26979) GGML_PAD(nbytes, alignment) wraps to 0 when nbytes is within (alignment - 1) of SIZE_MAX, which silently bypassed the size overflow guard in gguf_init_from_reader. Reject the tensor before padding when nbytes + (alignment - 1) would overflow. Adds a test-gguf handcrafted case (F32, ne = [4, 2^30-1, 2^30+1, 1]) whose ggml_nbytes = 2^64 - 16 lands in the wrap window. Fails on master, passes with the guard.
