/**
 * Plugin Name: Terminus Output Test
 * Description: A WP-CLI command that counts to 250k with a 5 second wait per increment.  Terminus is not passing WP-CLI output back to the terminal - As a result, the connection is closed after 10 minutes while the CLI command continues in the remote container with no way to stop it.
 * Usage: terminus wp site.env --verbose -- terminus-output-test
 * Version: 1.0
 * Author: Terrance Orletsky / ChatGPT
