## Title

    [W&B Weave] Auth conflict: "Both WANDB_API_KEY and WANDB_IDENTITY_TOKEN_FILE are set, which is not allowed."

## Body

    Cause (Documented platform behavior): Credential resolution rejects ambiguous configuration.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/wandb/weave/e1f58c90975b12aa188aa07d3e491859ee560b42/weave/wandb_interface/auth.py (official_docs, unknown, documented_behavior): get_wandb_credentials raises AuthenticationError when both WANDB_API_KEY and WANDB_IDENTITY_TOKEN_FILE are set.
    
    Search phrasings: weave WANDB_IDENTITY_TOKEN_FILE WANDB_API_KEY both set; wandb identity token file authentication error
    
    Evidence basis (self-declared by the contributing chat client): public_source.
