Replace ku with lfk in Developer Tools

[floatdrop]

Replaces bjarneo/ku (#86) with janosmiko/lfk as the Kubernetes TUI. lfk navigates the cluster through three yazi-style Miller columns over the owner hierarchy, so a Deployment opens into its ReplicaSets and Pods, and it integrates Helm management and trivy image scanning. It is the more mature project: twice the age, 898 stars, 18 contributors, packaged for Homebrew, winget, scoop, apt, dnf, AUR and Nix, with CI, coverage and an OpenSSF scorecard. One Kubernetes TUI is enough for the category, so ku goes.
