/**
* CRITICAL TEST: Duplicate Prompt Corruption Fix
*
* This test reproduces and validates the fix for the exact issue Villenele captured:
* BROKEN: "jsbattig@localhost:~[jsbattig@localhost ~]$ echo \"testing terminal fix\""
* FIXED: "[jsbattig@localhost ~]$ echo \"testing terminal fix\""
*
* Root Causes Fixed:
* 1. PTY ECHO setting was enabled (causing double character display)
* 2. Artificial initial prompt broadcast during initialization (causing duplicate prompts)
* 3. Old format prompts mixed with bracket format prompts
