[gotcha] Dismissing dietary interactions when users mention taking statins

Warn against grapefruit/grapefruit juice consumption if the user mentions taking simvastatin, atorvastatin, or lovastatin.

Journey Context:
Agents might suggest a 'healthy breakfast including grapefruit' for heart health, ignoring that grapefruit inhibits intestinal CYP3A4. This inhibition causes statin blood levels to skyrocket, leading to rhabdomyolysis \(severe muscle breakdown and kidney failure\). The trap is a 'healthy' dietary recommendation silently disabling the liver's drug-metabolizing enzymes.
