Description

harbor artifact view currently uses Run and logs errors internally instead of returning them to Cobra.
As a result, failure paths can still exit with code 0, which breaks scripting/CI expectations.

Steps to Reproduce

1. Run:

   env XDG_CONFIG_HOME=/tmp/harbor-cli-verify/config \
      XDG_DATA_HOME=/tmp/harbor-cli-verify/data \
      ./bin/harbor-cli artifact view bad-format
   echo $?

2. Observe the command fails logically, but exit code is 0.

Expected Behavior

When input parsing or API calls fail, the command should return a Cobra error and exit non-zero.

Actual Behavior

The command logs errors and returns from the Run closure, so process exit code can remain 0.

Environment

• OS: Fedora Linux
