[gotcha] Ignoring dietary context when users mention taking statins or calcium channel blockers

Explicitly warn against grapefruit/grapefruit juice consumption when a user mentions taking statins \(e.g., simvastatin, atorvastatin\) or certain blood pressure medications.

Journey Context:
Grapefruit seems like a healthy, harmless drink. However, it contains furanocoumarins that irreversibly inhibit intestinal CYP3A4 enzymes. This prevents drug metabolism, causing systemic drug levels to skyrocket \(up to 5x\), leading to rhabdomyolysis \(statins\) or severe hypotension. Agents often miss food-drug interactions because they seem benign compared to drug-drug interactions.
