fix: properly handle CLI arguments (#2368)

Fix CLI arguments not being respected. This happened due to the addition of category-based logging (--help, --version) and changes to the window loading ( --channels), respectively.

When handling --channels, I took the liberty to refactor the previous version of window description (which relied on generating JSON) to directly building the WindowLayout.
