Problem

Given a list of deployment steps as strings, write a Python function that validates and executes them in order for a simple web application deployment workflow. Each step is one of: build, test, package, deploy, verify. Return the ordered list of executed steps if the workflow is valid. If a step appears out of order, is duplicated, or an unknown step is present, return [].

Constraints

1 <= len(steps) <= 10
Each steps[i] is a non-empty lowercase string
Valid workflow order is exactly build -> test -> package -> deploy -> verify
A valid step may appear at most once
