Allow creating applications and libraries in separate folders for better project structure.

[ V ] Feature request

Currently both applications and libraries placed in same directory.
And there is only one config for this: `newProjectRoot`

Please add another one: `newLibraryRoot` - if set, libraries would be stored there.

Start by locating how the CLI reads `newProjectRoot` in its configuration schema and project-generation entry points, then inspect any existing tests for library creation. Done means a configured `newLibraryRoot` places newly generated libraries there while existing application placement remains unchanged.
