Add a SYCL code-generation backend mirroring the existing OpenCL backend. - gimmik/sycl.py: SYCLMatMul (platform='sycl'), registered in __init__ - gimmik/kernels/sycl/: cstream, bstream, bstream-msplit, cstream-ksplit Mako templates emitting self-contained launcher functions of the form `sycl::event kname(sycl::queue& q, ...)`, using local_accessor and nd_range for the shared-memory kernels. Supports fp32/fp64, beta, static- and dynamic-n signatures, and the fp32 float2 vector variants. - bench/: OpenCL-vs-SYCL benchmark and a correctness-validation suite that checks every generated kernel against a NumPy reference. - README: mention SYCL support.

Is there a use-case for SYCL? Our expectation was that those working on SYCL would consume the OpenCL kernels. |

Summary
Adds a SYCL code-generation backend to GiMMiK, mirroring the structure of the existing OpenCL backend.
gimmik/sycl.py—SYCLMatMul(platform='sycl'), registered ingimmik/__init__.py.gimmik/kernels/sycl/— Mako templates for thecstream,bstream,bstream-msplit, andcstream-ksplitkernels. Each emits a self-contained launcher of the formsycl::event kname(sycl::queue& q, ...)that submits the kernel to a queue. Shared-memory kernels usesycl::local_accessorandnd_range.betaterm, both static-nand dynamic-nsignatures, and the fp32float2vectorised variants — matching the OpenCL backend's feature set.bench/— a small harness (OpenCL vs SYCL) plus a correctness-validation suite.The generated code compiles with any SYCL 2020 compiler (tested with Intel oneAPI DPC++).
Test plan
SYCLMatMul(...).kernels(dtype)generates all variants for fp32/fp64.float2vector kernels. All pass.
