Model-Saver now writes SWA pattern for 15 architectures.

The official source reports this update: b11039: Model-Saver: Write the SWA pattern, 15 more architectures roundtrip. Model-Saver: Write the SWA pattern, 15 more architectures roundtrip ( #29042 ) llama: read the SWA pattern as a period or a per-layer array Add llama_model_base::load_swa_pattern(), which reads sliding_window_pattern either as one flag per layer or as a period expanded by set_swa_pattern(), and use it in every loader that reads the key as a period. These loaders silently ignored an array and applied their default period, although the converters of olmo2, gemma3n and exaone4 write arrays. The published GGUFs match the defaults, so their outputs do not change.
