• refactor: extract model loader bug fixes to another PR

• feat: add gguf_init_from_callback

• fix: always require a max expected size

• fix: change gguf_reader_callback_t's output type to void *, change max_expected_size and offsets to uint64_t

• fix: harden against offset overflow in buffer read

• fix: remove seek behavior from the callback

• feat: max_chunk_read == 0 means SIZE_MAX

• fix: seeking in a gguf file with no tensors
