test(startup): isolate compact invoke handler (#37)

- Issue #37: Windows still overflowed when startup IPC ran from the WebView2 load callback.
- Release the renderer startup gate on the next event-loop task after load returns.
- Keep logger and console forwarding behind the same post-load boundary.

Fixes #37.
