• Add build.exe: one-click Windows builder, vendor jni.h

  …

  build.exe downloads a portable mingw toolchain (w64devkit, pinned) into a
  subfolder on first run — nothing installed system-wide, no admin — then
  compiles the DLL and loader directly with g++, mirroring the Makefile's flags
  and source list, and prints the DLL imports to confirm the static link held.
  Source is build_bootstrap.c.
  
  jni.h is now vendored under third_party/jni, so no JDK is needed by either
  build.exe or make. JAVA_INC is optional and only overrides the vendored header;
  the Makefile picks up third_party/jni and adds -I<JAVA_INC> only when set.
  
  BUILD.md leads with build.exe; the make paths (Linux, MSYS2, WinLibs) stay for
  anyone who prefers it. Verified the exact recipe build.exe runs still links to a
  DLL importing only KERNEL32/USER32/GDI32/OPENGL32/msvcrt.
