fix(backend): strip release-type suffixes from YTM search title + extend stopwords

Browse Source 
- "recognize - Single" title → search uses "recognize" (strips "- Single/EP/Album/…")
- Adds Single/EP/Remaster/Deluxe/… to titleKws STOPWORDS so they never become
  mandatory title-match filters (no YouTube video title contains "Single")
