Ville Vesilehto 9a57d9693c fix(caddyfile): infinite loop on unclosed braces (#7571)
Update coredns/caddy to a version where Dispenser.NextBlock()
checks Next() and stops at EOF. This ensures forward progress
and prevents an infinite loop when a block is missing a closing '}'
under certain conditions.

Added a regression test.
