fix(ui): always show /init command in autocomplete

The /init command was only offered in the autocomplete when the current session had no messages yet, and it was filtered out entirely once any message existed. Since the underlying session.command endpoint works in any session, keep /init available whenever a session exists so AGENTS.md setup stays reachable mid-conversation.
