REM Build the BackstageInjection DLL for Windows x64 using cargo (GNU target).
REM The GNU toolchain is required: the reflective loader manually maps the image
REM without the MSVC CRT bootstrapping, and the MSVC CRT's TLS/CFG machinery
REM fast-fails (0xC0000409) under a manual map. The loader itself is pure Rust
REM (BackstageInjection-Rust/src/reflective.rs). Requires the
REM x86_64-pc-windows-gnu target.
