* Interactive Terminal Epic Restoration E2E Test

* CRITICAL TEST: End-to-end validation of the restored Interactive Terminal Epic functionality.
* Tests the complete user flow: Type → Enter → Execute → Response → Continue typing.
*
* PURPOSE: Verify that the git versioning fix and protocol alignment have successfully
* restored the terminal functionality that was lost during rollbacks.
