Problems fixed:
1. gen_patch.py was reading .muh YAML (all nulls) instead of C++ headers.
Now it parses bi100_* structs directly from tuning_*.cuh via regex,
extracts constexpr values, and maps them to vllm injection points.
Verified: 11 patches generated from 6 algorithms.
2. C++ headers had no build system or tests.
Added CMakeLists.txt (header-only library target) and compile_test.cpp.
Verified: g++ -std=c++17 compiles all headers, 17/17 runtime checks pass.
Also added cuda_compile_test.cu for when nvcc is available.
3. baseline.muh had a tuning section full of nulls duplicating C++ values.
Stripped to vllm launch config only. Tuning values live exclusively
in muh/include/muh/tuning/tuning_*.cuh bi100_* structs.
4. Fixed constexpr goto in tuning_scan.cuh (C++17 doesn't allow goto in
constexpr; replaced with early-return + default: break pattern).
Data flow is now:
tuning_*.cuh (bi100_* constexpr) ──→ gen_patch.py ──→ vllm patches
baseline.muh (launch config) ──→ gen_yaml.py ──→ computility-run.yaml
compile_test.cpp ──→ g++/nvcc ──→ verify values are real
