//!
// NOTE: All `.clone()` calls in this module are Safe - they are necessary for:
// - HashMap key ownership for statistics aggregation (stage_type.clone())
// - Data structure ownership transfers across model boundaries
//!
//! This module contains the core data structures used throughout the Pierre MCP Server.
//! These models provide a unified representation of fitness data from various providers
//! like Strava and Fitbit.
//!
//! ## Design Principles
//!
//! - **Provider Agnostic**: Models abstract away provider-specific differences
//! - **Extensible**: Optional fields accommodate different provider capabilities
//! - **Serializable**: All models support JSON serialization for MCP protocol
//! - **Type Safe**: Strong typing prevents common data handling errors
//!
//! ## Core Models
//!
//! - `Activity`: Represents a single fitness activity (run, ride, etc.)
//! - `Athlete`: User profile information
//! - `Stats`: Aggregated fitness statistics
//! - `PersonalRecord`: Individual performance records
//! - `SportType`: Enumeration of supported activity types
