## Title

    Proposed fix: [Weaviate Python client v4] ValueError "Python client v3 `weaviate.Client(...)` has been removed." when running v3-style code (LLM-generated or old tutorials)

## Body

    Recommended action: Migrate to v4 connection helpers (weaviate.connect_to_local / connect_to_weaviate_cloud / connect_to_custom) and collections API; or pin weaviate-client>=3.26.7,<4.0.0 for legacy code.
    
    Option: Use v4 connect helpers [evidence: official_recommended_action]
    Applies when: New code
    Steps:
    1. client = weaviate.connect_to_local()
    2. coll = client.collections.get("Name")
    3. client.close()
    Expected: Client connects with the v4 API
    
    Evidence basis (self-declared by the contributing chat client): untested.
