bug: `make install-kubectl` fails — missing install_kubectl.sh script

[magicsunday]

Problem

make install-kubectl fails with:

./scripts/install_kubectl.sh
make: ./scripts/install_kubectl.sh: No such file or directory
make: *** [Makefile.d/user.mk:163: install-kubectl] Error 127

Root Cause

The target in Makefile.d/user.mk:163 calls ./scripts/install_kubectl.sh, but this script does not exist. The catalog entry catalog/kubectl.json defines install_method: "github_release_binary", and the backend installer scripts/installers/github_release_binary.sh exists.

The generic scripts/install_tool.sh already supports this tool:

$ ./scripts/install_tool.sh kubectl install

Fix

Option A (recommended): Change the Makefile target to use the generic installer:

install-kubectl: scripts-perms ## Install Kubernetes CLI
	./scripts/install_tool.sh kubectl install

Option B: Create a thin scripts/install_kubectl.sh wrapper:

#!/usr/bin/env bash
set -euo pipefail
DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
ACTION="${1:-install}"
exec "$DIR/install_tool.sh" kubectl "$ACTION"

Option A is preferred — it reduces script proliferation and uses the catalog system consistently.

Also affected

The dynamic targets make upgrade-kubectl and make uninstall-kubectl call ./scripts/install_kubectl.sh update / uninstall and fail for the same reason.
