## 📈 Prometheus Metrics

- **A new Metrics tab on Pods** charts CPU, memory, network, and filesystem usage per container, sourced directly from Prometheus.
- **PersistentVolumeClaims get a Metrics tab too**, with kubelet volume stats (capacity, usage, inodes) and, for Carina volumes, custom Volume I/O metrics.
- **Auto-discovery finds Prometheus** in your cluster, or you can configure it manually from Settings → Monitoring, with per-context layering and a connection test.
- **An option to hide unavailable metrics** keeps the tab focused on panels that actually have data.

## 🚀 Karpenter

- **NodePool, NodeClaim, and NodeClass list and overview pages**, with capacity, disruption, and requirement details.
- **Block/Allow Disruption toggle** on NodeClaims, and relations linking NodePools, NodeClaims, Nodes, and NodeClasses.
- **Pods, CPU, and Memory Allocation columns** added to Nodes and NodeClaims.

## ✨ Other Improvements

- **The Restarts column now folds in the last restart's exit code**, colour-matched between the badge and the reason, with screen-reader support.

## 🐛 Fixes

- **List copy actions now route through the Wails clipboard** instead of the browser one.

## 🧹 Misc / Chore

- Bumped frontend and Go dependencies, and pinned `kube-openapi` to the version Kubernetes 0.37.1 expects.
