Implement MatchingEngine in internal/rulematcher package to enable configurable DNS policy rule evaluation order and behavior. New components: - MatchingConfig: Configuration for rule order and stop behavior - MatchingEngine: Orchestrates rule matching with configurable order - MatchingResult: Standardized result structure - DefaultMatchingConfig(): Maintains backward compatibility Key features: - Configurable rule evaluation order (e.g., domain-first, MAC-first) - StopOnFirstMatch configuration option - Graceful handling of invalid rule types - Comprehensive test coverage for all scenarios The engine supports custom matching strategies while preserving the default Networks → Macs → Domains order for backward compatibility. This enables future configuration-driven rule matching without breaking existing functionality.
