[BUG] /context command output lost colors after v2.1.20

What's Wrong?

The /context command output is now monochrome (no colors). The output no longer includes ANSI color escape codes.

Previously, different categories (system prompt, messages, free space, autocompact buffer) were visually distinguished by color.

What Should Happen?

The /context output should display colors to distinguish different categories, as it did in v2.1.19 and earlier.

Additional Information

This appears to be a side effect of the fix for #20391 (duplicate output in /context).

v2.1.20 changelog states:

Fixed duplicate output in commands like /context

The duplicate output bug is fixed, but colors were lost in the process.
