新增 mid_ac_count / hard_ac_count，去重统计中等和困难难度的 AC 题数。 在此之前所有成就对水题和难题一视同仁，这是最缺的一个维度。 增量走 build_ctx 新增的 problem_difficulty，它只在首次 AC 时才查库—— 绝大多数提交都不是首次 AC，无条件预查等于给每次判题白加一条 SQL。 删除 min_ac_code_chars：线上实测 1314 个用户的分布，最小值 8、p5=10， 有道题 8 个字符就能通过，这个指标测的是"谁做过那道水题"而不是 "谁写得简洁"，配不出有意义的成就。 自检里写死 min_ac_code_chars 的两处改成按 lte 成就自动发现： _check_registry 不再要求某个具体指标存在，_check_min_metric_absent 改为遍历所有上架的 lte 成就检查其指标。没有 lte 成就时 SKIP， 将来配了自动开始检查。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
