fix(ai): 修复自动分析管道 — 补全建议生成 + 事件发布

自动分析批处理（auto_analysis.rs）在完成流式分析后仅保存结果，
缺少三个关键步骤导致关怀引擎无法启动：
1. 不解析双通道输出（StructuredOutput）→ 无结构化建议
2. 不调用 SuggestionService.create_suggestions() → 无建议记录
3. 不发布 ai.analysis.completed 事件 → 下游消费者无感知

修复方案：提取 post_process_analysis() 共享函数，统一处理
解析→创建建议→发布事件的后处理逻辑，SSE handler 和自动分析共用。
