address CodeRabbit issues and use NonePlatform for zero-worker test Addressed CodeRabbit review feedback: 1. Use cancellable ctx instead of testContext in WaitForGuestClient 2. Add safe type assertions with comma-ok checks for condition parsing 3. Fix confusing log output by removing negated booleans Framework fix: 4. Use NonePlatform instead of globalOpts.Platform to skip framework validation that expects worker nodes. This matches the approach used by TestHAEtcdChaos for zero-worker scenarios. The test validates OVN control plane behavior with zero workers, which is platform-agnostic. NonePlatform allows the test to focus on OVN-specific validation without requiring cloud provider resources or worker nodes.

This causes ValidateHostedClusterConditions to expect worker-dependent conditions (DataPlaneConnectionAvailable, ControlPlaneConnectionAvailable, ClusterVersionAvailable) that cannot be satisfied in zero-worker cluster configurations. This commit adds ExecuteWithoutEnsureValidation() method that: - Skips the problematic after() validation (EnsureHostedCluster) - Still runs before() validation which correctly uses opts.ExpectedNodeCount() - Allows tests to provide their own comprehensive validation - Is specifically designed for non-standard cluster configurations The TestOVNControlPlaneZeroWorkers test is updated to use this new method, as it already provides comprehensive Steps 1-8 validation for OVN components in zero-worker clusters. This fixes the CI failure where the test timed out waiting for conditions that cannot be met without worker nodes.
