[gotcha] Grapefruit and Statin CYP3A4 Inhibition Leading to Rhabdomyolysis

Explicitly warn against grapefruit/grapefruit juice consumption when generating guidance for simvastatin, atorvastatin, or lovastatin.

Journey Context:
Agents often focus on drug-drug interactions but miss drug-food interactions. Grapefruit irreversibly inhibits intestinal CYP3A4, causing systemic statin levels to spike dramatically. This leads to rhabdomyolysis \(rapid muscle breakdown and acute kidney failure\). It is a silent trap because the food seems benign.
