REM build_prime_ui.bat — Build prime_ui.exe (Windows TUI for quantum-prime library)
REM
REM Usage:
REM   build_prime_ui.bat          (default: clang)
REM   build_prime_ui.bat --gcc    (MinGW GCC)
REM   build_prime_ui.bat --msvc   (MSVC cl.exe)
REM   build_prime_ui.bat --all    (all three compilers)
REM
REM Outputs: prime_ui.exe  prime_ui_gcc.exe  prime_ui_msvc.exe
