* feat(helm): add persistent volume for local model cache
When using local reranker (e.g., BAAI/bge-reranker-v2-m3) or local
embedding models, the models are downloaded to /home/hindsight/.cache
on every pod restart, causing slow startup and unnecessary bandwidth.
Add optional persistent volume support:
- api: PVC mounted at /home/hindsight/.cache
- worker: volumeClaimTemplate (StatefulSet) at same path
Disabled by default. Enable via:
api.persistence.modelCache.enabled: true
worker.persistence.modelCache.enabled: true
Closes#860

* feat(helm): add extraVolumes and extraVolumeMounts for api and worker
Allow users to mount arbitrary volumes (configMaps, secrets, emptyDir,
etc.) into api and worker pods via values, following common helm chart
library conventions.
