when build fails, it throws error but process do not exit

When a build fails especially on frontend, we see it throws an error but process don't exit. Due to it the build just hangs instead of exiting.

server-webpack error ModuleNotFoundError: Module not found: Error: Can't resolve 'apollo-link-scalar' in '/Users/fullstack-pro/servers/frontend-server/src/modules'
    at factory.create (/Users/fullstack-pro/node_modules/webpack/lib/Compilation.js:925:10)

The fix I have found that work is by replacing this line https://github.com/sysgears/larix/blob/master/packages/zen/src/executor.ts#L121 with process.exit(1). Let me know if you want me to send PR.

@veeramarni I think in that place process.exit would be bad, because it will terminate the process during watch mode, which is not desired. I think exit on error during build should be taken care of via this line:
https://github.com/sysgears/larix/blob/master/packages/zen/src/executor.ts#L1243
Can you try to troubleshoot on your project why this place doesn't get triggered?
