[Bug]: ANSI Code Broken Render in CLI

[CooperWang0912]

Bug Description

When running hermes setup or similar commands such as hermes model, the interactive wizard fails to render terminal colors and box-drawing elements correctly. The ANSI escape sequences (like [35m and [0m) are being printed as literal text prefixed by an unparseable character string rather than being interpreted by the terminal. This happens in both CMD and Powershell.

Screenshots

Steps to Reproduce

1. Open Windows Terminal (PowerShell or CMD).
2. Run hermes setup.
3. Observe broken render for the CLI.

Expected Behavior

The terminal should interpret the escape codes to render colored text and borders cleanly without displaying raw [35m or [0m strings.

Actual Behavior

The CLI render is broken.

Root Cause Analysis

This is likely caused by incorrect ANSI setup in the installer script. I will look into it and see if I can locate the exact issue.

Proposed Fix

Replace faulty ANSI setup with the correct rendering code.
