## Title

    Proposed fix: [MCP Go SDK] ElicitForm rejected: 'elicit schema property "x" contains nested properties, only primitive properties are allowed' / 'has unsupported format' / 'has enum values but type is

## Body

    Recommended action: Flatten the schema to top-level primitive properties (split nested structs into separate fields), use supported formats, and string enums.
    
    Option: Flatten the elicitation schema [evidence: official_recommended_action]
    Applies when: See trigger
    Steps:
    1. Use a dedicated flat struct for elicitation
    2. Replace nested objects with separate primitive fields
    Expected: Error no longer occurs
