Key features: - IRegexEngine and IRegexPattern abstractions for engine-agnostic regex operations - SystemRegexEngine: wraps System.Text.RegularExpressions.Regex - PcreRegexEngine: wraps PCRE.NET for PCRE2 support - RegexEngineFactory: centralized engine creation and default engine management - Full backward compatibility with existing SubstitutionRule API - Comprehensive test coverage for both engines - Example demonstrating engine switching capabilities The implementation maintains full backward compatibility while enabling users to leverage PCRE2's advanced features when needed. Users can switch engines globally via RegexEngineFactory.SetDefaultEngine() or use specific engines per rule.
