* wip(v3): 移植监控与整理韧性修复到 v3 基线 包含：监控看门狗隔离/挂载探测、整理队列持久化、文件系统子进程代理、 写入原子化。迁移重挂到 v3 链 8a4c7e1d2f90 -> 7f5c1d2e3a4b -> e3d9f4b7c806。 tmdb 相关测试尚未通过，待定位。 * fix(v3): 修正移植引入的 16 项测试失败 - poller.py：合并时我方保留的行仍用旧变量名 merged_snapshot，而 v3 已统一 改名为 current_snapshot，导致 NameError 被外层 except 吞掉、快照从未保存 - smb.py：采纳 f-string 拆分写法，恢复 Python 3.11 可解析 - dispatcher 测试：历史查重由 _should_skip_by_history 统一承担，mock 点随之调整 - tmdb 缓存测试：补充 v3 新增的 media_source/media_id 字段 - tmdb 重试测试：为 fake 补充 match_multi/async_match_multi 尚余 3 项与 v3 识别流程的连接失败处理有关，待单独判断。 * fix(v3): 测试适配 v3 的 media_source/media_id 重构 v3 将媒体标识从 tmdbid 统一重构为 media_source + media_id，recognize_media 的 tmdbid 参数已被 **kwargs 静默吞掉——传了也不生效，流程会误降级到名称搜索。 tmdb 重试用例改用新参数后恢复正确路径。 同时修正 fake 的 match_multi 语义：真实实现（tmdbapi.match_multi）吞掉所有 异常并返回 None，连接失败与「未找到」在该路径上本就不可区分，fake 需保持一致。 至此移植引入的 19 项失败全部清零。 --------- Co-authored-by: Aqr-K <Aqr-K@users.noreply.github.com>
