recallTmdbCandidates searches cn then en names in the preferred language by type and fetches details for a bounded set of candidates (MP alias fallback); translations become aliases; bindAuto no longer registers generic or alias-only site titles; snapshot/feed title changes reparse and force a re-resolve that unbinds when it can no longer confirm.

* 身份识别的 TMDB 候选召回(ID-2),对照 MoviePilot TheMovieDbModule._prepare_search_names + TmdbApi 的
|
|
* __search_movie_by_name / __search_tv_by_name / _candidate_resolution:
|
|
* - 名称顺序 [中文名, 英文名](MP:cn_name → 简体 cn_name → en_name);
|
|
* - 按类型搜索(剧集线索只搜 tv,否则 movie + tv),单语言(首选语言,与 MP 相同);
|
|
* - 搜索结果的标题/原标题都对不上名称时,按年份相近度取前几个拉详情,用别名 + 译名比对(MP 对全部候选逐个拉详情,
|
|
* 这里设上限,打分交给 domain.resolveIdentity)。
|
|
* 与 MP 的差异:MP 在第一个命中处短路,这里收集候选池交给证据打分(同名多候选 → 进待识别池而不是取第一个)。
