"""身份匹配差分:用 MP 上游 MetaInfo + TheMovieDbModule 的名称识别链生成 mp.json。

用法(MP 仓库根目录,用其 .venv;TMDB 走本地缓存代理,见 docs/porting/moviepilot-identity-match.md):
  cd /opt/moviepilot-plus/upstream/MoviePilot && PYTHONPATH=. TMDB_PROXY=http://127.0.0.1:18731 \
  .venv/bin/python /opt/uhd_media_tool/packages/domain/test/differential/identity/gen-identity-mp.py

按 MP 实际识别顺序:MetaInfo(title, subtitle) → _prepare_search_names(cn_name, 简体 cn_name, en_name)
→ 逐个名称 _search_by_name(_build_match_plan:电视剧 [季年份+年份, 无年份];其他 [电影+年份, 电视剧+年份, multi])。
不含识别缓存、插件辅助识别与详情补全(只取匹配到的 id/类型/名称/年份)。只记录行为输出,不复制 MP 源码。
