The MDNS component has been refactored from a single monolithic file mdns.c into a set of focused modules with clear responsibilities. This restructuring maintains the same functionality while improving code organization, maintainability, and testability. In the stage#2 we will focus on module based tests In the stage#3 we will focus on small scale refators and optimizations
