What's the feature?

Description

Replace all type stubs with production-ready Rust types following Swift SDK's proven success pattern. This is the foundation layer that must be rock solid before building client architecture.

Current State: Types are stubbed as String (e.g., pub type User = String;)
Target State: Proper Rust structs with serde integration

Success Metrics

• Zero type stubs remaining in generated code
• All API models have proper field types and validation
• Comprehensive error types with context
• All type generation tests passing

Child Issues

• Rust SDK: Replace type stubs with proper Rust structs #8177
• Rust SDK: Generate API-specific error types #8178
• Rust SDK: Add comprehensive type generation tests #8179
• Rust SDK: Implement serde integration for all types #8180
