// 1. Target config — x86_64-windows-gnu, optimised+stripped (unless Debug).
// 2. Single-threaded — no TLS, Zig runtime stays minimal.
// 3. Assembly: arch/hells_gate.s — Hell's Gate SSN encryption + Hell Descent arg dispatch.
// 4. Link system DLLs: kernel32, ntdll, advapi32, crypt32 (Go handles the rest via manual map).
// 5. Output: valak.dll — Go's reflective loader copies this from zig-out/bin/ to implant/core/.
