Upgrade llama.cpp from b9150 to b9151

Key changes in b9151:
- New LOG_TRC macro (trace level between INFO=3 and DEBUG=5)
- New common_params_print_info() consolidates build/device/system info logging;
  replace the two-line LOG_INF pattern in jllama.cpp with a single call
- common_init() now defaults log prefix and timestamps to true (opt-out via
  --no-log-prefix / --no-log-timestamps)
- New SLT_TRC / SRV_TRC server macros; many verbose server messages demoted
  from INF to TRC (less noise at default verbosity)
- server_slot gains periodic in-flight throughput printing (print_timings_tg/pp)

All 417 C++ unit tests pass.

 | ~b9145–b9150 | `src/unicode.cpp` | New `unicode_regex_split_custom_qwen35()` function registered for the Qwen 3.5 tokenizer regex pattern; uses `[\p{L}\p{M}]+` letter-plus-combining-mark runs vs. Qwen2's `\p{L}+`; additive internal tokenizer change, no project changes required |
 | ~b9145–b9150 | `ggml/src/ggml-cpu/ggml-cpu-riscv64-spacemit/` | SpaceMIT RISC-V IME backend major refactor: IME2 kernels, expanded quantization (Q2_K, Q3_K, Q6_K, Q8_0, Q5_0, Q5_1, Q5_K, MXFP4), TCM (Tightly Coupled Memory) pool; new source files `ime2_kernels.cpp`, `ime_env.cpp`, `repack.cpp`, `rvv_kernels.cpp`, `spine_mem_pool.cpp`; guarded by `GGML_CPU_RISCV64_SPACEMIT` build flag; no project changes required |

+| ~b9150–b9151 | `common/common.h` + `common/common.cpp` | New `common_params_print_info(const common_params &)` function: prints verbosity level, per-device memory (name, total, free), and system info at `LOG_INF` level; replaces the two-line pattern `LOG_INF("build_info: %s\n", llama_build_info()); LOG_INF("%s\n", common_params_get_system_info(params).c_str());` — updated in `jllama.cpp` |
