Add a monorepo for small single-purpose CLI tools that share a common library, so tools reuse TUI primitives and Kubernetes client bootstrapping instead of duplicating them. - common/tui: direction markers, style palette, width-aware padding/layout - common/kube: in-cluster→kubeconfig client loading + core/metrics clients - podgap: live TUI comparing pod requests/limits vs actual usage, with up/down markers showing per-pod change since the last refresh - Makefile auto-discovers tool directories: make <tool> | all | install
