jnc upgrade

Checks if there are newer versions of dependencies and upgrades them by loosening the version constraints in the manifest file. Unlike jnc update, which respects existing version constraints, upgrade temporarily removes version pins to find the latest available versions, then updates both the lock file and the manifest. By default, all features and their dependencies are upgraded.
