Extension process remains running when parent process terminates

[John Pywtorak]

Describe the bug
The docs indicate here https://neutralino.js.org/docs/how-to/extensions-overview/ to exit the process when the socket is closed; However, adding or ensuring process.exit() is called does not change the child process behavior. The child extension process remains running, orphaned.

To Reproduce
Steps to reproduce the behavior:

1. Run the sample extension with fix to path \\ double backslash.
2. Close the webview2 window.
3. Node process still running.

Expected behavior
Child dies

Specifications
Windows 11
Neu 5.1.0

FYI: Procs below is a rust replacement for ps

The node.exe process does linger and is orphaned. See the proc output below. You can see neutralino-win_x64.exe spawns the process 33620, then I kill / exit / close, the neutralino-win_x64.exe process and the node process remains running. And I know it is the child by pid and cli args.
