audio_win.ll implements audio.ll's snd_* contract over XAudio2 from IR: a
source voice per clip, restart on play, LoopCount for loops, SetVolume,
SetFrequencyRatio and a balance pan through SetOutputMatrix, with the COM
slots taken from the SDK's xaudio2.h. Clips are RIFF WAVE read through
lp_pak_open (weakly referenced), so a packed sound loads directly. ludicc links
it with xaudio2 and ole32, and silences xinput.lib's importeddllmain warning.
Verified: ludic-dev test 135/135, selfhost-test 32/32; on the PC a harness
loads, plays, pans, loops and stops clips, and Maroon Lake windowed reports
"sound: 31 of 31 clips loaded".

win32.ll implements cocoa.ll's contracts over user32 and xinput: the message
pump, the held-key set and frame key in Ludic codes, the mouse with raw input
for cursor mode 2, clip-based cursor modes released on focus loss, XInput pads,
and the software framebuffer present. win32_gl.ll puts the WGL 4.1 core context
on that window (vsync, borderless full screen); gl_win.ll's context code is now
lgl_wgl_core, shared with the headless hidden window, whose win_gl_* stubs move
to gl_win_nowin.ll. audio_win.ll links Audio.* silently for now.
Verified: macOS fixpoint, ludic-dev test 135/135, selfhost-test 32/32; on the
PC gl_triangle renders identically headless and in a real window, and Maroon
Lake builds windowed and runs a playtest to frame 240 in the desktop session.

gl_win.ll creates a hidden-window WGL 4.1 core context and carries gl.ll's
float/memory helpers, with ldexp and QueryPerformanceCounter in place of the
libSystem calls. glgen now also writes gl_thunks_win.ll: the same 478 thunks,
calling through pointers that @lgl_win_load fills from wglGetProcAddress (and
opengl32.dll for GL 1.1). ludicc links the pair against opengl32/gdi32/user32
on a Windows target.
Verified: gl_api.ludic and gl_thunks.ll regenerate byte-identically, ludic-dev
test 135/135, selfhost-test 32/32, and headless gl_triangle on an RTX 3070 Ti
matches the macOS frame to within one level per channel.

--target <triple> (default: the host, from OS=Windows_NT) selects the Windows
runtime. emit_win.ludic defines the POSIX names the backend already calls over
the UCRT and Win32 in IR, so rename replaces an existing file, ftell is 64-bit,
and fopen is binary. Known folders follow %APPDATA% / %LOCALAPPDATA% / %TEMP%,
and the driver speaks cmd.exe, writes .exe outputs and finds LLVM's clang.
Verified: macOS three-stage fixpoint, ludic-dev test 135/135, and on Windows
the Mac-emitted Windows IR and the Windows-built compiler's IR are identical
through two generations.
