[Bug] Syntax Highlighting Breaks with Complex Formatting

Bug Description
The user-message syntax highlighting does not work when the message includes some formatting. For example, this message ```./run_test.sh chess-bench-lazy.md
Creating new test directory:

engine's playing strength and computational speed",

stronger playing ability compared to its current

These goals/requirements are not clear enough. The
user asked for a massive task, and the degree of
improvement is not clear. The understand agent
shoudl have used the messageUser tool to clarify
further. Improve the prompt (don't overtune though)
in the
@src/config/agents/understand.prompt-config.ts so
that it knows these tasks need to be better. Don't
make it code-specific—bear in mind the goal of teh
overall system (
@.docs/internal-docs/upeara-summary.md ). Ultrathink
on this``` caused the gray-background-highlighting to turn on and off throughout the message.
