fix: MSVC build support, modern theme, vergilius fnptr import

- CMake: detect MSVC↔MinGW Qt ABI mismatch at configure time (#10)
- CMake: add /utf-8 /MP for MSVC builds
- CMake: fix theme/example deployment for multi-config generators (MSVC)
- Auto-run windeployqt post-build so correct Qt DLLs are always deployed
- Add Modern theme (dark blue with cyan/purple/amber accents)
- Vergilius import: handle function pointer typedefs
