AI Summary: This issue requests that Orion implement support for exit codes, similar to kube-burner, to provide clearer status indications after execution. The proposed exit codes include 0 for normal completion, 1 for unrecoverable errors, and 2 for detected performance regressions. This would enhance automation and interpretation of Orion's benchmark results.

AI Summary: Implement a new `orion version` command-line option that displays the current version of the Orion tool, similar to existing commands in kube-burner and kube-burner-ocp. This should leverage existing tagged releases.
