Feature Proposal: Expand deterministic incident diagnostics (explain.rs) to PVCs and Services

1. Describe the problem

sofka's X incident view (explain.rs) provides deterministic, evidence-based diagnostic explanations for workloads and pods. However, when inspecting other core resources like PersistentVolumeClaims (PVCs) or Services, explain.rs currently falls back to generic event lists (explain_generic), leaving common failure modes without detailed diagnostics.

2. How you handle it now

Currently, when a PVC is stuck in Pending or a Service is failing to route traffic, users must manually switch views, inspect describe outputs, check StorageClass names, or manually match pod labels to verify endpoint counts.

3. How the proposed feature would help

Adding dedicated explain_pvc and explain_service diagnostics directly in src/explain.rs will automatically surface:

• PVCs: Claim status (Bound, Pending, Lost), StorageClass, requested storage, volume targets, and resize conditions.
• Services: LoadBalancer IP allocation status, ClusterIP/Headless status, and matching pod endpoint readiness (X/Y pods ready matching selector).

We have implemented this logic and verified it with pure unit tests under src/explain.rs.
