西风逍遥游 811eff1c3a ci(quality): warnings-as-errors gate, sanitizers, smoke, Python lint/tests 
- EVENGINE_ENABLE_STRICT_WARNINGS option: MSVC /W4 /WX, GCC/Clang
  -Wall -Wextra -Werror, with documented noise suppressions and
  -isystem/-external:I for third-party headers; enabled on the
  Windows/Linux debug CI jobs.
- Fix warnings across engine, modules and tests exposed by the gate,
  including real bugs (incomplete-type deletes, Timespan microsecond
  overflow, overload hiding, enum switch gaps, dead code).
- Add Linux ASan+UBSan job, example smoke step, python-tools test
  job, ruff config (scripts+tools), weekly Linux coverage job and a
  CodeQL workflow.

西风逍遥游 4377e062dd feat: zeroerr parameter validation + Doxygen API documentation 
Squashed onto current main. Adds src/engine/common/Assert.h (EV_PARAM_CHECK / EV_ASSERT backed by zeroerr), an EVENGINE_ENABLE_ASSERTS option (non-Debug builds strip ZEROERR_NO_ASSERT unless enabled), parameter checks at key entry points, Doxygen comments across headers, Doxyfile + make docs / CMake docs targets, and Windows setup + code conventions in AGENTS.md.

西风逍遥游 228b5a0f15 docs: add Doxygen API comments, docs target, and Windows AGENTS.md 
Normalize all header comments to Doxygen @brief form and fill in missing class/method docs across engine common, cmdline, and module headers (~2368 @brief entries). Add root Doxyfile, 'make docs' target, CMake docs target, .gitignore for docs/api, README/docs/dev updates, and a Windows (native) + code-conventions section in AGENTS.md.

西风逍遥游 cff9bb4d0c tensor: AITemplate-style compile pipeline, gpgpu Sequence, mini-LLM demo and weight-only quantization 
Refactor the tensor module around AITemplate-style static compilation:

- Optimizer: DCE, constant folding, elementwise chain fusion, matmul/conv
  bias+activation epilogue fusion, liveness-based static memory planning,
  topological group execution order.
- KernelGen: shape-baked GLSL per fused group; two-pass softmax/layernorm;
  shared-memory SDPA; naive + 16x16 tiled matmul templates.
- GpuBackend: arena buffer allocation per memory plan, matmul autotuning,
  single command-buffer submission via the new gpgpu::Sequence (uploads,
  dispatches and downloads recorded once per run, Kompute-style).
- shaderc in-process GLSL->SPIR-V on Windows (no glslc.exe dependency),
  with glslc spawn fallback.
- CPU reference kernels shared by eager and the compiled interpreter;
  no-Vulkan fallback keeps compiled graphs runnable headless.

Neural-network coverage: softmax/logsoftmax, layernorm/rmsnorm (with
weight/bias), gelu/silu, conv1d/conv2d, pool, embedding, concat/slice,
axis reduces, argmax, cast, fused SDPA (+masked), resize2d, batched
matmul, seeded random.

Weight-only quantization (activations stay fp32):
- fp16 (IEEE half), fp8 (e4m3), fp4 (e2m1), int8, int4 with per-group
  block scales (MXFP-style: scale = maxAbs / format max magnitude).
- Quantized weights capture into graph Const nodes; CPU interpreter
  dequantizes at materialization; GPU matmul/embedding kernels dequantize
  inline from packed uint buffers (naive matmul variant).
- TF::quantizeWeight API + script binding.

Mini-LLM validation (TinyStories-gpt2-3M, 8 layers d=64):
- test/tensor_llm.cpp builds the full GPT-2 graph from engine ops and
  matches numpy reference: probs within 3e-7, greedy generation 24/24
  identical (~100 ms/token CPU), compiled path exact.
- tensor.llm.quantizedDtypes: fp16/int8/fp8/int4 all keep 16/16 greedy
  top-1 (fp4 16/16 with proper block scaling), weights 27.6 MB -> 3.3-13 MB.
- scripts/export_tiny_gpt2.py converts a PyTorch .bin checkpoint (no torch
  dependency) plus GPT-2 tokenizer into engine assets + numpy reference.

Tests: gpgpu 8/8, tensor 31/31 (original suite) + tensor.llm.* + tensor.quant.*
Assets in test/assets/mini_llm are gitignored (regenerate via the script).
