## What changed
Add a presentation-only `UserVerificationView` with explicit verify and cancel choices, request details, and a waiting state. Report decisions through a callback, suppress duplicate approvals while waiting, and allow cancellation before or during verification. Dismiss the view when its matching MCP elicitation request resolves.
Add a full-screen request details overlay that can be opened without making a decision. Wrap prompt text and long URLs for narrow terminals. The view is not yet connected to incoming verification requests.
## Testing
Add tests and snapshots covering prompt and waiting rendering, narrow layouts, long URLs, duplicate approval suppression, cancellation, matching request dismissal, and full-screen inspection and scrolling.
