fix(music): 缩写点号还原与包含/演出后缀弱匹配修复失配

- metamusic: 连续单字母空格序列还原为点号缩写（S H E -> S.H.E），
  在场景点分之后执行避免点号再被压平
- metamusic: 规格段残留判定收紧，发布组短词仅在格式词无空格连字符
  形态（FLAC-HHWEB）放行，修复自然语言曲名（Ashielf Alpen）被误剥
- musicbrainz: 专辑候选新增包含关系弱匹配（原声带条目带额外前缀）
  与演出后缀弱匹配（S.H.E十七音乐会 -> 条目「十七」）
- 补充 metamusic 缩写还原与 musicbrainz 弱匹配测试案例
