清理城市农业类别 + 修复采集器LLM直接选题

清理:
- sustainability_cases.json移除GLO-001/CHN-001城市农业案例,替换为循环消费
- initial_cases.json移除case8东京垂直农场/case26城市屋顶农场
- strategy_topics_to_json.py移除B01/B05/D05三个种菜选题
- collector.py移除城市农业→循环消费映射,更新注释
- 删除fix_collector.py/test_image_gen.py/generate_images.py等遗留脚本
- 删除import_topics.py和automation/下旧版生成脚本

修复:
- collector.py _generate_topic_with_llm不再依赖搜索结果,无搜索时LLM直接生成
- run()始终调用LLM,不再要求web_search_results非空
- 替换sources.yaml中已失效的RSS源(澎湃/虎嗅/中新网→36氪/少数派)
