llama.cpp 合併 K2 Horizon 支援，修復 Windows GGUF 無法載入

model : add K2 Horizon dense and MoVA support ( #29535 ) model: K2 Horizon gguf conversion code model: loading hparams and tensors in k2-horizon.cpp model: K2 Horizon compute graph model: K2 Horizon compute graph adjustment and registering tokenizers model: K2 Horizon chat template and accomodate safetensors naming unicode : add the K2-Horizon pre-tokenizer splitter The K2-Horizon regex had no arm in unicode_regex_split_custom and fell through to the general std::regex fallback, which fails two ways. On MSVC std::regex rejects \p{...}, so no K2-Horizon GGUF loads on Windows at all: llama-quantize, llama-imatrix and llama-perplexity all abort with regex_error(error_escape) before a token is produced. Where the fallback does compile it is still wrong. unicode_regex_split collapses each codepoint to a single byte naming its Unicode category before matching, and U+200C/U+200D are category Control, which has no entry in k_ucat_cpt, so both become the 0xD0 fallback byte. The literal ‌ and ‍ alternatives in K2's regex can then never match and every ZWNJ or ZWJ ends a letter run. The splitter is the existing llama3 one with a single rule widened, since K2's regex differs from llama3's only in that a letter run also takes marks, ZWNJ and ZWJ. tests/test-unicode.cpp gains a case for this: it fails before the change with [Amy] [ZWNJ khaham] and passes after with the run intact. tests: expand K2 Horizon unicode splitter coverage unicode: handle K2 Horizon case folding and empty input Assisted-by: Codex jinja : support sequence indices in selectattr and rejectattr Assisted-by: Codex model : add K2 Horizon dense and MoVA support Includes the K2 Horizon implementation from ifm-ai/llama.cpp with converter, tensor-parallel and model save/reload fixes. Assisted-by: Codex chat : support K2 Horizon reasoning and tool calls Assisted-by: Codex conversion: remove obsolete K2 Aurora alias Assisted-by: Codex k2-horizon: enforce response schemas and load YaRN betas Constrain final JSON after reasoning, accept flexible JSON tool envelopes, enforce XML dialects, and handle repeated or alternate thinking markers. Load YaRN beta metadata instead of retaining the default values. Add schema, streaming, continuation, and model reload regressions. Validate CUDA and CPU builds and 0.9B, 4B, and MoVA conversation/tool round trips.
