[counterintuitive] Using 'Output ONLY the code, no markdown backticks' to prevent conversational wrapping

Use structured outputs or parse the model's standard markdown code blocks programmatically instead of trying to suppress them via prompt.

Journey Context:
Models are trained to output markdown with code blocks. Prompting them to 'output only code' fights against their training data, often leading to erratic formatting \(e.g., outputting code but without newlines, or still adding backticks\). The robust solution is to accept the model's natural markdown output and parse the content within the code blocks, or use structured outputs to separate code from explanation natively.
