Webhook-based interaction.followup.send() messages don't trigger Discord mention notifications even with proper allowed_mentions settings. Fix: use channel.send() for content with mentions, and send ephemeral followup to satisfy interaction response requirement. Also need defer(ephemeral=True) for followup to be ephemeral.
