fix(internal/logic/root): resolve gh command issue

- updated cdLogic function to properly handle use of gh command
- updated main Root function to check specifically for flags when gh
  command is used

This commit should make the 'hkup --' functionality more robust to user
args for both git and gh commands. For example this should work when
running 'gh repo clone <url> [<customdir>] -- --bare'.
