ClickOnce Delivery Test

Click the button to trigger the ClickOnce .application handler.
Tests: Edge ClickOnce flag + dfsvc trust prompt + launcher execution on a clean machine.

Run ClickOnce Test
Expected on a clean machine (no autoclicker):
1. Edge: "Do you want to open this file?" → Open
2. dfsvc: "Application Run — Security Warning. Publisher: AIWORM Test." → Run
3. SmartScreen blue screen? → "More info" → "Run anyway" (if this does NOT appear, ClickOnce manifest signature suppresses it — good)
4. Success marker: %TEMP%\aiworm_clickonce_test.txt + MessageBox popup.
