- Shorten backprop tests to prevent timeout
- Add line number of failing test
- matmul: remove unused enable_bind
- allocator: we will retain enable_bind there
- mat: disable cyclic padding optimization (broken)

This change adds a basic C API that allows access to Gemma functionality from other programming languages. The functionality is exposed via a shared library (DLL on Windows), with C++ interfaces and a basic C# interop wrapper included.
To build the DLL, use the `windows-dll` preset, which includes the C and C++ sources as follows:
```
cmake --preset windows-dll
cmake --build --config Release --preset windows-dll -j 4
```
This should generate a `gemma.dll` in `<build-dir>/Release`.
To build for non-Windows, the appropriate C++ DLL linking will need to be done to generate a shared library for the target OS.

- Added prompt flag to InferenceArgs for non-interactive mode
- Set user-facing options to verbosity level 1
- Fixed prompt_size declaration and variable ordering in run.cc
- Properly set prompt_size after WrapAndTokenize calls
- Moved kVerboseLogTokens block after prompt_size is set
This change adds a --prompt command-line option that allows users to
provide prompts directly without entering interactive mode, which is
useful for scripting and automation.
use new ThreadingContext2 instead of monostate/init in each frontend
Add ThreadingArgs(replaces AppArgs)
backprop: use Packed() accessor and MakePacked factory and row-based access to allow for stride
compress_weights: remove, moving to py-only exporter instead
Move MatPtr to mat.h and revise interface:
- Generic MatOwner
- rename accessors to Packed*
- support stride/row accessors, fix RowPtr stride
Add TypeBits(Type)
Move GenerateMat to test_util-inl for sharing between matmul test/bench
Move internal init to gemma.cc to avoid duplication
Rename GemmaEnv model_ to gemma_ for disambiguating vs upcoming ModelStorage
Remove --compressed_weights, use --weights instead.
tensor_index: add ExtentsFromInfo and TensorIndexLLM/Img
Allocator: use normal unique_ptr for AllocBytes so users can call directly
threading: use -> because AlignedPtr no longer assumes arrays

Gemma receives a MatMulEnv arg, with comment on lifetime
Split threading into topology so the latter can be used in allocator
Add AllocClasses() for non-POD (ThreadPool)
Support binding pool to NUMA node
Update threading_test with latency measurements
Also update Highway version.

Adds Stride to ConstMat, to support decompression of C output for test
matmul_test: add line numbers to output
Also ignore "N is not a multiple of nc" when N==nc

This computes softmax on the top-K logits, instead of computing softmax first and then getting top-K probs. So we end up avoiding renormalizing too. Additionally, modify softmax to do temperature scaling, if temp != 1.0
