[gotcha] Recommending St. John's Wort for mild depression without checking for SSRI usage

Explicitly contraindicate St. John's Wort if the user is on SSRIs, SNRIs, or MAOIs due to the risk of Serotonin Syndrome.

Journey Context:
Users often ask about 'natural' remedies, and models might suggest St. John's Wort as it has evidence for mild depression. However, it is a potent serotonin reuptake inhibitor and CYP450 inducer. Combining it with prescription SSRIs can cause fatal Serotonin Syndrome. Models often fail to cross-reference supplements with prescription meds.
