• test(persistence): add comprehensive cache volume tests

  Add helm-unittest tests for dedicated cache volume persistence:
  - Default emptyDir behavior
  - PVC creation when enabled
  - hostPath configuration
  - Volume mount verification
  - PVC size, access mode, storage class configuration
  - Annotations support
  - Existing claim usage
  - Type-specific behavior (pvc vs hostPath vs emptyDir)
  
  Add NOTES.txt with persistence information:
  - Show config, media, and cache volume types
  - Display cache volume details when enabled
  - Benefits explanation for cache volume
  - Warning for hostPath usage
  
  Tests ensure cache persistence works correctly for all scenarios.

• feat(persistence): add cache volume persistence support

  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
