[Windows] Browser opens before executor is ready

[ifTNT]

Description:

On the Windows version, the browser may open prematurely before the executor is fully initialized. This can result in the error message "[Sorry, there are no workers available to handle your request, please report this to an admin or try again later]" from the executor.

Steps to Reproduce:

1. Launch the Kuwa Windows version.
2. Immediately ask a question to an executor before it is fully registered with the Kernel.

Expected Behavior:

The browser should only open after all necessary components of Kuwa are initialized, including the executor, to prevent displaying misleading error messages.

Environment:

• Operating System: Windows 11
• Browser: Edge
• Kuwa Version: v0.3.3
