feat: multi-call binary

[Noxsios]

For embedded CLIs under UDS-CLI (zarf, maru, yq, k9s, etc...) add the ability for UDS-CLI to be a multi-call binary (like busybox).

Describe the solution you'd like

• Given UDS-CLI is symlinked as zarf or kubectl, etc...
• When the CLI is called via one of these symlinks
• Then the CLI runs as though it is that binary

func main() {
    switch filepath.Base(os.Args[0]) {
    case "zarf":
    ...
    case "kubectl"
    ...
    case "k9s"
    ...
    case "uds-monitor"
    ...
    default:
    cmd.Execute()
}
