Windows guest VMI core: host library, CLI, guest agent

Static library over a flat RW mmap of guest RAM: GPA/GVA paging walks,
beacon-driven bootstrap, dynamic struct-offset profiling, process and
module enumeration, a region map, and value/pointer/signature scanners on
a shared windowed sweep. Public API in include/; internals under src/.

Thin CLI demonstrator over the public API. Guest agent cross-compiled to
Windows x86-64 via mingw-w64. CMake: static library + CLI + guest target,
C17.
