Align docs, examples, the setup wizard, and telemetry tests with the
current Doubao multimodal embedding model so generated configs keep
referencing the supported default consistently.
The Helm chart shipped with OpenAI as the default model provider but
OpenViking is a volcengine project. Switch embedding/vlm defaults to
doubao series, add the required root_api_key field, add missing
storage.vectordb/agfs config sections, and guard against replicaCount>1
which causes RocksDB lock contention on a single PVC.
Closes#724
Adds a complete Helm chart at deploy/helm/openviking/ with:
- Deployment with Recreate strategy (RocksDB single-writer)
- PVC for persistent data storage
- ConfigMap for ov.conf configuration
- Optional ingress support
- Health probes matching Dockerfile HEALTHCHECK
- Configurable resources, replicas, and all ov.conf settings
- Installation guide at deploy/helm/README.md
