Fix

The fix addresses the root cause with minimal, focused changes to the userInfo function:

1. Removed the nil detail variable — The original code declared var detail *http.Request which was always nil, then dereferenced it via detail.Host, causing the nil pointer dereference panic on every request to /user.

2. Used the existing r parameter instead — The function already receives a valid *http.Request as r, so r.Host is the correct way to access the request's host.

3. Added proper handling for unknown users — Used the two-value map lookup (displayName, ok := users[username]) to detect unknown usernames and return a 404 Not Found response instead of silently returning empty data.
