Initial sacred_re scaffold with borderless fullscreen mod

- Launcher (sacred_re.exe) starts sacred.exe with sacred_re.dll injected
  via Detours; the DLL verifies the Sacred Gold 2.28 build before hooking.
- Hook framework: RE_HOOK for game addresses, RE_HOOK_API for Windows
  APIs, per-hook enable/disable in sacred_re.ini, sacred_re.log.
- Game code: Log (0x66f1c0) hooked, CmdLineHasFlag (0x813140) rewritten.
- Borderless mod: forces windowed mode, covers the monitor, scales the
  1024x768 image aspect-correct, remaps mouse input, keeps running in the
  background with keyboard input hidden while unfocused.
- CMake/Ninja/MSVC x86 build, VS Code setup, disasm tool, function map.
