fix(#2377): extract handle_agent_status — drop clippy::too_many_lines allow

dispatch was 101 lines (1 over limit) due to the AgentStatus arm.
Extract it to a dedicated handle_agent_status helper to bring dispatch
under the 100-line lint limit without the allow attribute.

Per mara review comment on PR #2379.
