【开源发布】llama.cpp v3.5

llama.cpp（ggml-org/llama.cpp）发布 v3.5。更新说明：The RDNA3.5 config table selects a 64-row / 128-thread tile up to J=32 and a 128-row / 256-thread tile above that. On gfx115x the smaller tile leaves enough LDS free for a second workgroup per CU, while the larger one does not. Extend the 64-row tile to the (type, J) pairs where it measured faster on gfx1151, and leave every other entry untouched. J=96 is deliberately excluded because it did not benefit. test-backend-ops perf on gfx1151, 100 MUL_MAT shapes over the affected types (N in 48..512, M both padded and unpadded), 3 rounds: median +2.1%, best +26.0%, no shape outside run-to-run noise.
