The Go module name has been changed from `carrot_bbs` to `with_you`, which requires all import paths to be updated throughout the codebase and by external consumers. BREAKING CHANGE: Module name changed from carrot_bbs to with_you. All imports and dependencies must be updated from carrot_bbs/* to with_you/*.
