• 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.

• Makefile: build on Windows too, and add BUILD.md

  …

  A cloner on Windows hit `make` failing with "The syntax of the command is
  incorrect." The recipes used a Unix shell — `mkdir -p`, `rm -rf`, and an
  `objdump | grep | sort` pipeline — which cmd.exe cannot run, so the build died
  before the compiler was ever invoked.
  
  Detect the OS (make sets OS=Windows_NT there) and pick the directory-make,
  tree-remove and dependency-dump commands each shell understands; use `$(@D)`
  so there is no trailing slash to trip cmd's quoting. JAVA_INC include is now
  quoted so a path like "C:/Program Files/Java/..." survives, and BUILD.md spells
  out the toolchain, the MSYS2/WinLibs paths, and the JDK include requirement.
  
  CXX/CC/OBJDUMP stay `:=`, not `?=`: make has a built-in default for CXX/CC
  (the host g++/cc), and `?=` would leave that in place and quietly build for the
  wrong platform. A command-line `make CXX=g++` still overrides `:=`.
  
  No change to the build output — same DLL, still importing only KERNEL32,
  USER32, GDI32, OPENGL32 and msvcrt.
