feat: initial release of headlamp-intel-gpu-plugin v0.1.0

Adds a Headlamp plugin for Intel GPU device plugin visibility:

- Dedicated sidebar section: Overview, Device Plugins, GPU Nodes, GPU Pods
- Native Node detail page injection: GPU capacity, allocatable, utilization, active pods
- Native Pod detail page injection: per-container GPU resource requests/limits
- Native Nodes table: GPU Type and GPU Devices columns
- App bar health badge (hidden when plugin not installed)
- GpuDevicePlugin CRD monitoring (deviceplugin.intel.com/v1) with graceful
  degradation when CRD is not present
- Supports discrete (i915), Xe, and integrated GPU nodes via node labels
- 48 unit tests, TypeScript clean, 28 kB production bundle

+/**
+ * headlamp-intel-gpu-plugin — entry point.
+ *
+ * Registers sidebar entries, routes, detail view sections, table column
+ * processors, and app bar action for Intel GPU device plugin visibility
+ * in Headlamp.
+ *
+ * Surfaces Intel GPU information in the following places:
+ *   - Dedicated sidebar section: Overview / Device Plugins / Nodes / Pods
+ *   - Native Node detail page: Intel GPU section (capacity, utilization, pods)
+ *   - Native Pod detail page: GPU resource requests per container
+ *   - Native Nodes table: GPU Type and GPU Devices columns
+ *   - App bar: health badge (hidden when plugin not installed)
