UX feedback: notify when something's wrong when installing or starting the server

[sinedied]

Sometimes the GenAIScript extension in VS Code get stuck while installing or starting the server. Bad internet connectivity is more likely to trigger the problem, especially during updates.

The trick to solve this is to stop and restart the server manually, but it's not obvious for new users.

One option would be to detect when the server fails to start and show up a notification, with maybe a "restart" button in the notification?

Thanks for the feedback. The issue description is clear in outlining the scenario where the extension gets stuck due to connectivity or server startup problems. It would be helpful to provide additional details:

• Which operating system(s) you experienced this on.
• Any relevant logs or error messages from the Output or Developer Tools tabs in VS Code when the problem occurs.
• How frequently this happens, and whether it occurs only during updates or also on fresh installs.
• If you notice any patterns (e.g., only with certain VS Code or GenAIScript versions).

These details will help the team investigate and prioritize the detection and notification improvements.

I keep track of the startup time, I will show a toast if it take more than 5s to start.

We could also default to use pnpm if available
