Email summary of findings

[jluk]

Goal

Send an email digest of findings so users don't have to check the UI.

Requirements

• Weekly scheduled email with new findings since last send
• Triggered alert for High threat findings (immediate)
• Clean HTML email template: claim, reality, threat level, link to detail
• Email address configured in Settings page (already stored in localStorage)
• Consider Resend or SendGrid for delivery

Notes

• Need a server-side scheduled trigger (Vercel Cron or similar)
• Email preference should eventually move from localStorage to user profile (after Clerk)
