查找 Pattern Tool - 从 pattern 库中获取符合条件概率阈值的 pattern

功能：
- 账号：读取 input/{账号}/处理后数据/pattern/pattern.json，条件概率基于账号人设树；
  元素与帖子选题点匹配走账号 match_data / point_match，并支持人设树子节点、兄弟节点扩展。
- 平台库：读取 input/xiaohongshu/pattern/processed_edge_data.json，条件概率基于 xiaohongshu/tree；
  元素匹配仅使用 input/xiaohongshu/match_data/{post_id}_匹配_all.json。
