## Title

    [KServe Hugging Face runtime] "Task couldn't be inferred from <Architecture>. Please manually set `task` option."

## Body

    Cause (Documented platform behavior): The runtime maps architecture suffixes to tasks; unknown ones require explicit --task.
    
    Fix status: documented_behavior
    
    Other error fragments:
