feat: initial release of headlamp-rook-ceph-plugin v0.1.0

Headlamp plugin for Rook-Ceph cluster visibility.

Pages:
- Overview dashboard: CephCluster health, capacity bar, resource counts
  (block pools, filesystems, object stores, PVs, PVCs), daemon pod
  health summary, non-Bound PVC alerts
- Block Pools: CephBlockPool table with replication, failure domain,
  mirroring; slide-in detail panel
- Pods: all Rook-Ceph daemon pods grouped by role with ready/total counts

Native Headlamp integrations:
- StorageClass table: Rook Type, Pool, Cluster ID columns
- PV table: Rook Type, Pool columns
- PVC detail injection: driver, type, pool, volume handle
- PV detail injection: CSI volume attributes
- Pod detail injection: Ceph daemon role badge
- App bar badge: cluster health (HEALTH_OK/WARN/ERR), color-coded

API / architecture:
- src/api/k8s.ts: types + filters for ceph.rook.io/v1 CRDs; handles
  both default rook-ceph.* and custom-namespace provisioner strings
- src/api/RookCephDataContext.tsx: shared context provider; fetches
  CephCluster, CephBlockPool, CephFilesystem, CephObjectStore CRDs
  plus daemon pods via label selectors
- 37 unit tests (vitest + @testing-library/react)
- TypeScript strict mode, zero any types
- CI + release GitHub Actions workflows
