Replace the placeholder ripgrep/fd/bat/fzf set with devops tooling, keeping jq: kubectl, helm, k9s, kubectx/kubens, stern, yq, OpenTofu, and terragrunt — all self-contained, statically linked release binaries in ~/.local/bin, so they persist across Kasm redeploys with no reinstall. Switch idempotency from parsing each tool's --version (kubectl/helm/k9s have no uniform flag) to a version stamp under ~/.local/bin/.versions, and add fetch_arch_deb() for the amd64/arm64 naming most devops tools use. Ansible is Python, not a single binary, so it gets its own module: a venv at ~/.local/opt/ansible with its CLIs symlinked into ~/.local/bin. The guard verifies ansible actually runs (a redeploy can wipe the system python the venv links to) and rebuilds if not. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
