> Raw CPUID and RDTSC access for Python via a tiny native DLL wrapped with ctypes. Exposes CPU feature detection (SSE/AVX/AES/etc.) and cycle-accurate timing that plain Python cannot do natively.

|
|
Windows x64 only for now. No Python C API used — a small MSVC-compiled DLL exports two functions (raw_cpuid, raw_rdtsc) loaded via ctypes.WinDLL, so it works across Python 3.10-3.13 without per-version ABI builds.

## Notes
|
|
|
|
- No MSR/register-write access — that requires ring 0, not reachable from usermode without a kernel driver
|
|
- Linux/macOS not supported yet
