"""
Integration test: update all configured repositories using
--clone-mode https and --no-verification.

This test is intended to be run inside the Docker container where:
  - network access is available,
  - the config/config.yaml is present,
  - and it is safe to perform real git operations.

It passes if BOTH commands complete successfully (in separate tests):
  1) pkgmgr update --all --clone-mode https --no-verification --system-update
  2) nix run .#pkgmgr -- update --all --clone-mode https --no-verification --system-update
