llama.cpp v0.3.0

## Overview llama.cpp 0.3.0 introduces the dots3-note multimodal model (with a new DSA-ISWA KV cache), MTP support for GLM-4.5-Air, and tensor-split () plus multi-sequence rollback fixes for DeepSeek 4. ggml is bumped to v0.22.0 (meta-backend tensor split, per-op Metal kernels with parallel compilation, non-in-place ), while mtmd gains dots3-note vision/audio, WebP decoding and a Pillow-accurate resize. The server adds a debug knob, and the web UI gets tabbed chat navigation. ### New models - Add dots3-note model with a new DSA-ISWA KV cache type ([#27060](https://github.com/ggml-org/llama.cpp/pull/27060)) ### Core changes - DeepSeek 4: add tensor-split mode via ([#26490](https://github.com/ggml-org/llama.cpp/pull/26490)) - DeepSeek 4: fix rollback with multiple sequences ([#26756](https://github.com/ggml-org/llama.cpp/pull/26756)) - Fix meta tensor split state propagation for tensor parallel ([#27574](https://github.com/ggml-org/llama.cpp/pull/27574)) - GLM-4.5-Air: add MTP (multi-token prediction) support ([#26534](https://github.com/ggml-org/llama.cpp/pull/26534)) - bailingmoe3: support DSpark ([#27508](https://github.com/ggml-org/llama.cpp/pull/27508)) - mamba2: flatten in/out projections to dispatch GEMM instead of GEMV ([#27513](https://github.com/ggml-org/llama.cpp/pull/27513)) - Models: use in deepseek2/4, dflash, minicpm3 and plm…
