Render ANSI Color Codes in Q's Chat Shell Execution Window

## Problem

When shell scripts that contain ANSI color codes are run inside the Q Chat's shell execution window, the ANSI color codes are not interpreted. Rather the escape characters are emitted directly, which makes the output for some scripts rather difficult to read.

## Expected behavior

It would be _fantastic_ if Q Chat's execution window could render ANSI color codes natively! It would make any colorized output from shell scripts visible (and beautiful) when rendered in the Q chat interface.

If that's too difficult to implement (hope not), it would be better to strip the unrecognized ANSI escape sequences as a fallback.

Start by locating the Q Chat shell execution window and tracing how shell output is rendered in the chat interface. Reproduce the issue with a shell script containing ANSI color codes, then determine whether the execution window can render those sequences or should strip them as a fallback. Done means colorized output is readable without raw escape characters.
