SignedApproval

This update strengthens how your approvals are verified and adds a new way to prove you're human in email. Face ID and passkey approvals now verify your identity through a cryptographically signed assertion end-to-end, closing a gap where a weaker verification method could be used instead of the one you set up, and fixing a bug that could trigger Face ID twice in a row. We've also brought Email Stamps to the app: verify your email identity right on your device and generate a signed, verifiable stamp — with a link, HTML badge, or plain-text fallback — that proves a real person authored your message. Under the hood, we updated several dependencies to patch known security advisories, with no change to how the app works.
