LexEQUAL: Multilexical Matching Operator in SQL

Summary: LexEQUAL introduces a multilexical matching operator for SQL that enables cross-language name and text similarity. It converts multilingual text to phonemic representations via T2P tools and canonical IPA/Unicode, then performs approximate phoneme matching; parameterizable for recall-precision tradeoffs; prototype on a relational DBMS shows practical multilingual data integration.
