Add dedicated cache volume configuration to reduce wear on SD cards and improve
performance by allowing cache to be stored on separate storage.
Changes:
- Add persistence.cache configuration in values.yaml with support for:
- PVC (default type when enabled)
- hostPath for direct host mount
- emptyDir (default when disabled)
- Add cache volume mount at /cache in deployment
- Add cache PersistentVolumeClaim template
- Support for existing PVC via existingClaim
- Configurable size (default 10Gi), accessMode, storageClass, and annotations
- Update Chart version from 2.5.0 to 2.5.1
- Add Artifact Hub changelog annotation
The cache volume is disabled by default to maintain backward compatibility.
Users can enable it via:
```yaml
persistence:
cache:
enabled: true
type: pvc
size: 10Gi
```
This addresses the use case mentioned in #62 where users want to avoid SD card
wear by storing cache on separate persistent storage.
Fixes: #62
