Local cluster command handling
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to The cleanup command may report success while leaving a local cluster behind if one deletion fails, creating a bounded local-environment cleanup issue. The PR is mergeable with explicit owner awareness and follow-up to propagate each deletion failure. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

Summary
This PR fixes several issues found while installing NVCF locally with the self-hosted CLI. The fixes apply to both single-cluster and multi-cluster workflows and cover control-plane and compute-plane installation.
Key Changes
Local cluster lifecycle
Before this fix, a failed cluster creation was followed by false success messages and an interactive context-selection prompt:
The lifecycle targets now propagate creation and startup failures and reach ensure-context only after success; stubbed k3d and kubectl tests cover these paths in CI.
First-time Helmfile installation
Before this fix, on a fresh cluster cert-manager had not been installed yet, so its ClusterIssuer CRD was unavailable when Helmfile tried to diff the new PKI release:
Apply operations now use --skip-diff-on-install, which skips diff only for releases that do not exist yet and allows their prerequisites to be installed first.
Helmfile state ordering
Before this fix, Helm 4 processed the helmfile.d state files in parallel because self-hosted install did not enable the detected runtime mode. Dependent services could start before the OpenBao (Vault-compatible) secret-injection components were ready, leaving their expected secret files missing:
The mode now reaches both control-plane and compute-plane rendering: the Helm 4 compatibility path adds --sequential-helmfiles and --track-mode helm-legacy, while the documented Helm 3 and Helmfile 1.1.x path remains sequential by default.
Local observability configuration
Before this fix, the local BDD fixtures enabled the optional observability stack without providing its local-bdd environment file:
The single-cluster and multi-cluster fixtures now explicitly disable observability without changing the reusable stack defaults.
Stargate transport configuration conflict
Before this fix, the local single-cluster fixture combined bundle-based transport trust with insecure Stargate QUIC, a configuration that is invalid in any topology:
The bundle-trust fixture now disables insecure QUIC; the multi-cluster BDD fixture intentionally retains insecure QUIC for its separate split-cluster routing scenario.
Local setup prerequisites
Local installation requires Helm, Helmfile 1.1.x, and the helm-diff plugin to apply the control-plane and compute-plane stacks.
Go 1.24 or later is required to build nvcf-cli from source, and these prerequisites are now documented across the local single-cluster and multi-cluster guides.
