- Closes https://github.com/enso-org/cloud-v2/issues/804
- The GUI should now properly configure deep links and auth settings, among other things, because the logic has been ported over from the GUI1 runner.
- The porting was very basic; it may be a good idea to refactor it later, but that is out of scope of this PR.
- This also means that `runner/` should be safe to remove along with GUI1 in the future, as all code relevant to GUI2 now resides in `app/gui2/runner`.
# Important Notes
- The built `ide2` has been tested on Windows, but should also be tested on macOS.
- Should *also* be fully tested in `npm run dev`.
