Boolean Expression Simplification for Query Optimization

Introduced a Boolean expression simplification engine to improve MongoDB query performance. This engine leverages a modified Quine–McCluskey algorithm and Petrick's method, operating on an efficient bitset representation of Boolean expressions. The simplification process reduces computational overhead and enables the query optimizer to generate more efficient execution plans, leading to significant throughput improvements and reduced execution times for complex queries. The implementation also addresses MQL's unique logical semantics, including negation and handling of missing values, ensuring correctness and performance gains.
