📝 Summary

Summary by CodeRabbit

• Tests
  • Added OpenShift end-to-end coverage for using the CLI in core mode with a namespace-scoped Argo CD instance. The test verifies that the CLI can list applications and create an automated nginx application in a managed destination namespace, and that the application becomes Healthy and Synced and appears in the CLI listing with those statuses.

Adds a parallel OpenShift end-to-end test that uses the argocd CLI in core mode to create an application and verify its Healthy and Synced statuses.

Changes: Core-mode CLI validation

Layer / File(s)	Summary
Core-mode CLI setup test/openshift/e2e/ginkgo/parallel/1-144_validate_argocd_cli_core_mode_test.go	Adds a core-mode CLI runner with a two-minute timeout and a helper that creates a temporary kubeconfig scoped to the Argo CD namespace. The helper removes the temporary file during cleanup.
Application creation and status validation test/openshift/e2e/ginkgo/parallel/1-144_validate_argocd_cli_core_mode_test.go	Adds a parallel test that creates an application with automated sync, self-heal, and pruning enabled. It checks that the Application becomes Healthy and Synced and that the CLI listing reports both statuses.

- Line 54: Update the core-mode CLI command execution around `exec.Command` and
`CombinedOutput` to use a context with a deadline for each `argocd app create`
and `argocd app list` invocation. Handle and report context timeout errors so a
blocked command cannot leave the spec waiting beyond its deadline.
- Line 73: Replace the direct os.ReadFile use for srcKubeconfig with Kubernetes
kubeconfig loading rules that merge multiple configured paths and flatten
relative certificate and key references before writing the temporary kubeconfig;
do not log credential contents.
- Line 167: Update the `Eventually` callback around the `app list` command to
return its output and error as `(string, error)` instead of asserting on
`listErr` inside the polling attempt, so transient CLI errors are retried within
the existing two-minute limit.
