- Added configuration management using Viper in internal/config/config.go - Implemented ClientConfig, ServerConfig, TLSConfig, HetznerConfig, UpstreamConfig, and main Config struct. - Created LoadConfig function to read and validate configuration files. - Developed Hetzner DNS provider in internal/provider/hetzner/hetzner.go with methods for updating DNS records. - Added comprehensive unit tests for configuration loading and Hetzner provider functionality. - Established HTTP server with metrics and update endpoint in internal/server/server.go. - Implemented request handling, authorization, and error management in the server. - Created integration tests for the Hetzner provider API interactions. - Removed legacy dynamic DNS integration tests in favor of the new API-based approach.
