/// Trait for Java download providers (Adoptium, Temurin, Corretto, etc.)
/// 
/// Implements SOLID principles:
/// - Single Responsibility: Each provider handles one download source
/// - Open/Closed: New providers can be added without modifying existing code
/// - Liskov Substitution: All providers are interchangeable
/// - Interface Segregation: Minimal required methods
/// - Dependency Inversion: Code depends on trait, not concrete implementations
