ScriptCut 0.1.1 Windows alpha

Native Windows 10/11 x64 alpha for ScriptCut.

• ScriptCut-Setup-0.1.1-x64.exe: assisted NSIS installer.
• ScriptCut-0.1.1-portable-x64.exe: portable build.
• Python, Node.js, and a separate FFmpeg installation are not required.
• The build is unsigned, so Windows SmartScreen may show a warning.
• Faster Whisper safely falls back from unsupported float16 GPUs to CPU.
• Long-stream waveforms are generated with bounded memory through FFmpeg.

This payload was promoted only after native Windows CI started the
packaged backend, rendered a vertical MP4 with ASS captions and a
censorship bleep, probed it with bundled FFprobe, and launched the
packaged ScriptCut.exe.
