SQL Expression Parser Library

This library provides a parser for SQL boolean expressions following the grammar defined in SqlExprParser-EBNF-Final.ebnf

The parser enforces type safety at the grammar level: all top-level expressions must evaluate to boolean values, while arithmetic and value expressions can only appear as operands to relational operators.
