"""Mouse interaction controller for hardware automation.
This module implements comprehensive mouse control capabilities including clicks,
movement, drag operations, and scrolling with security validation and performance
optimization for universal UI automation.
Security: All operations include coordinate validation and rate limiting.
Performance: Optimized event generation with smooth movement algorithms.
Type Safety: Complete integration with hardware event type system.
