🔧 Update Go version in go.mod and enhance build process with versioning information. Modify Makefile and Taskfile to inject build metadata (version, commit, build time) into the binary. Improve README with instructions for custom version builds and document new build info features. Add benchmarks for message parsing and processing to improve performance testing capabilities.
