* llama : refactor sampling_info to use buffer_view template
This commit updates the sampling_info struct in llama-context to use a
buffer_view template for the logits, probs, sampled tokens, and
candidates buffers.
The motivation for this is to simplify the code, improve type safety
and readability.
CCCL 3.2 has been released since it was added to llama.cpp as part of
the backend-sampling PR, and it makes sense to update from RC to final
released version.

Resolves: #18560
Implement ggml_cann_mul_mat_id_quant function to support quantized matrix
multiplication for Mixture of Experts (MoE) architectures on CANN backend.
Key features:
- Support Q4_0 and Q8_0 quantized weight formats
- Use IndexSelect to dynamically route expert-specific weights based on indices
- Leverage WeightQuantBatchMatmulV2 for efficient quantized computation
- Handle automatic F16 type conversion for hardware compatibility
- Support both per-expert and broadcast input modes
Implementation details:
- Extract expert weights and scales using CANN IndexSelect operation
- Process each batch and expert combination independently
- Create proper tensor views with correct stride for matmul operations
- Automatic input/output type casting to/from F16 as needed
Testing: All test cases passed for supported types (F32, F16, Q4_0, Q8_0).

* gguf-py: Bump sentencepiece version
There's a new version that's been out for a while that addresses the issues mentioned in https://github.com/ggml-org/llama.cpp/pull/14200. There's a long chain of reasons I would like this change, but the short version is that it allows people who use both `sentencepiece` and `gguf` to take advantage of these fixes. On conda-forge, currently, it locks the version (since there is no notion of optional dependencies).
Regardless, I don't think this should be too controversial.
* review feedback

* Add binary.wgsl: unified shader with conditionals for all 4 ops
* Add gen_binary_shaders.cpp: build tool for using pre_wgsl preprocessor
* Remove bin_op.tmpl.wgsl and binary.wgsl (Python template)
* Update CMake to generate binary operator shaders at build time
* ggml-webgpu: migrate binary ops to JIT compilation with overlap handling
* port binary operators from AOT to pre-wgsl JIT compilation
* add src1=dst overlap handling for binary ops
* use compile-time workgroup size defines instead of runtime overrides
* ggml-webgpu: complete overlap handling for binary ops
* add support for inplace & overlap case in binding setup
* restructure conditional logic to handle all overlap cases
* ensure all buffer bindings are correctly assigned for edge cases
* ggml-webgpu: remove unused binary overlap cases
Remove src0==src1 binary overlap case that never occurs in practice.
* keep INPLACE (src0==dst), OVERLAP (src1==dst), DEFAULT
* remove unused src0==src1 and all-same variant
* refactor wgsl to eliminate duplication
