Chuchotage for Windows preview

This is a test build for Windows 10/11 x64.

How to run:
1. Unzip the folder.
2. Open Chuchotage.exe.
3. Enter your OpenAI API key, or leave the field empty if you intentionally want to try local Codex/ChatGPT auth on that Windows account.
4. Choose the audio device to capture and the device for translated playback.

Notes:
- This preview is not Microsoft Store-signed yet, so Windows SmartScreen or company endpoint security may warn or block it.
- It does not require administrator rights, install drivers, or create a Windows service.
- For the cleanest test, route the source app audio to one Windows playback device and translated playback to headphones.
- Single-headset mode depends on Windows process-loopback support and may vary by Windows build, headset, and meeting app.
