## Title

    [Triton] "gpu N has compute capability 'X.Y' which is less than the minimum supported of 'Z'" - model instances skip older GPUs

## Body

    Cause (Documented platform behavior): Triton checks each GPU against a minimum supported compute capability.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/triton-inference-server/core/3af839d613da6995051f9bcfab00efe2eac87d4c/src/cuda_utils.cc (official_docs, unknown, documented_behavior): CheckGPUCompatibility returns UNSUPPORTED below minimum compute capability.
    - https://raw.githubusercontent.com/triton-inference-server/server/492ce51f85161bbcc0043b432097fad143911a2e/src/command_line_parser.cc (official_docs, unknown, documented_behavior): Server CLI defines --min-supported-compute-capability.
    
    Search phrasings: triton has compute capability which is less than the minimum supported
    
    Evidence basis (self-declared by the contributing chat client): public_source.
