Matches the keywords 'multi', 'dual', or 'ita-eng' when they appear as standalone tokens delimited by whitespace or dots, capturing the surrounding separator characters too. Commonly used in Radarr custom formats or release restrictions to detect and avoid multi-language/dual-audio releases (e.g., Italian-English tracks). The lookahead assertions prevent matching these words when embedded inside larger words.
