What this PR does
A2A agent discovery derives a service base URL from the agent-card URL. Python URL parsing removes the brackets required around IPv6 literals, so https://[2001:db8::7]:8443/.well-known/agent-card.json was persisted as the invalid URL https://2001:db8::7:8443.
This change restores brackets when the parsed hostname is an IPv6 literal while preserving the existing behavior for hostnames, ports, paths, and user-info removal.
