feat(cli): autostart without a console window

This moves `komorebic` logic into a `lib.rs` file and calls it from `main.rs` (normal behavior) and then there is a second binary `komorebic-no-console` binary that uses `#![windows_subsystem = "windows"]` which tells the linker to not attach a console window to this binary.
