- Add OpenAIRerankClient using standard flat request/response format
compatible with DashScope compatible-api and other OpenAI/Cohere-style
rerank APIs (no input/output wrappers)
- Fix silent data corruption: add index bounds-checking so out-of-bounds
or missing index returns None with a warning
- Add provider allow-list validation in RerankConfig ('vikingdb'|'openai')
- Remove unnecessary getattr() in RerankClient.from_config()
- Update ov.conf.example: keep vikingdb (doubao) as primary rerank config,
add rerank_openai_example section for DashScope qwen3-rerank
- Update docs (en/zh): add OpenAI-compatible provider example alongside
existing volcengine example in configuration guide and schema
- Add 24 tests covering success, edge cases, and factory dispatch
