Code Review

This pull request adds a new function, demo_shellcheck_break, to Backend/test/smoke_test.sh. The new function uses echo to print a variable's content. Feedback suggests replacing echo with printf for improved reliability and portability, as echo can behave inconsistently across different shell implementations.

[gemini-code-assist]

Using echo to print variable content can be unreliable. It can misinterpret values that look like options (e.g., -n) and handle backslash escape sequences inconsistently across different shell implementations. For printing arbitrary data, printf is a safer and more portable alternative.

Suggested change

	echo "$name"
	printf "%s\n" "$name"
