In-memory auth codes are ephemeral — they're wiped on server restart.
Previously, codes were only visible via email delivery. If the server
restarted between OTP send and OTP verify, the code would be lost.
Now memory.AuthCodeRepository.Create() always logs the code to stdout
with a [DEV] prefix. This gives developers a reliable fallback regardless
of whether NOTIFY_URL is set. Updated CLAUDE.md to document this behavior
and the DEV_USER_EMAIL env var.
