//! Exchange call message types - nested enum with role-based categorization.
//!
//! # Adding New Operations
//!
//! 1. Determine the role/category: Who is authorized to call this operation?
//!    - User? Vault leader? Specific admin? Anyone?
//! 2. Add the variant to the appropriate *Action enum
//! 3. Choose a NEVER used explicit discriminant: `NewOperation { ... } = N,`
//! 4. Add handler function and update dispatch
//! 5. NEVER change existing discriminants, reorder variants/fields, change types
