Extension Email Verification

This adds click-to-verify email functionality to Caffeine AI apps, handling the full flow from sending verification links to tracking verified addresses. You get a prefab mixin that processes the verification callbacks and a `verifiedEmails` module that maintains state. It depends on the separate email extension for actual sending. The setup is straightforward: include the mixin, call `sendVerificationEmail` with a template containing the `{{VERIFICATION_URL}}` placeholder, and check verification status with `contains`. Good for user registration flows where you need proof of email ownership. The example code shows a typical pattern with user profiles and email uniqueness checks. Works on Caffeine AI Plus and Pro plans.
