## Title

    [Pinecone Python SDK 10] query now fails locally: "top_k must be between 1 and 10000, got N" on all lanes

## Body

    Cause (Documented platform behavior): SDK 10 applies a shared client-side range check. The server ceiling is a deployment setting and can be lower, arriving as ApiError.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/pinecone-io/pinecone-python-client/f9550510fa076ff7c9bbccd310ceaa7c57c0ffd6/docs/migration/v10-migration.md (official_docs, unknown, documented_behavior): Breaking-changes item 1: top_k range 1-10000 checked locally on Index, AsyncIndex, GrpcIndex; deployments can be lower and reject with ApiError.
    
    Search phrasings: pinecone top_k must be between 1 and 10000; pinecone query top_k limit error
    
    Evidence basis (self-declared by the contributing chat client): public_source.
