Change

Start a controlled smoke run's exit countdown after its first rendered frame. Windows native graphics initialization exceeded the previous four second wall-clock limit in the alpha.7 packaging workflow, leaving the last reported frame count at zero despite a clean exit.

Validation

• Added a process-level regression with startup longer than the smoke duration.
• All three LauncherSourceTest checks pass locally.
• Linux and both macOS architecture packages passed the original native smoke gate; Windows will run the same rendering requirement after this fix.
