## Title

    [Vertex AI Agent Engine] resource_limits validation: 'Memory size of X is too large. Must be smaller than 32Gi.' / 'requires at least N CPUs' / cpu must be one of 1, 2, 4, 6, 8

## Body

    Cause (Documented platform behavior): Agent Engine only accepts cpu in {1,2,4,6,8}, memory in Gi below 32Gi, with minimum CPU per memory size.
    
    Fix status: documented_behavior
    
    Other error fragments:
    - is too large. Must be smaller than 32Gi.
    - resource_limits must contain 'cpu' and 'memory' keys.
    - must be a string ending with 'Gi'. Got
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/googleapis/python-aiplatform/6da2b9b5352798893cc009ca83a1578f91994a51/vertexai/_genai/_agent_engines_utils.py (official_docs, unknown, documented_behavior): Validates resource_limits keys, CPU set, Gi suffix, 32Gi cap and min CPUs per memory.
    
    Search phrasings: agent engine resource_limits memory 32Gi; vertex agent engine cpu must be one of 1 2 4 6 8
    
    Evidence basis (self-declared by the contributing chat client): public_source.
