PHPStan on steroids

PHPStan 2.1.34 brings significant performance improvements after 6 weeks of optimization work. The release achieves 25-40% faster analysis times in real-world projects, with internal benchmarks showing 50% runtime improvements. Key optimizations include reduced bootstrap overhead for mutation testing with InfectionPHP (70% fewer files analyzed, 40% faster invocations). The improvements reduce CI pipeline energy consumption and developer wait times, though the release requires more memory with fixes planned for future versions.
