Module algorithm 

Rate limiting algorithm trait and implementations.

This module defines the Algorithm trait and provides implementations for various rate limiting algorithms.

Available Algorithms

• GCRA (gcra feature): Generic Cell Rate Algorithm - precise, low memory
• Token Bucket (default): Controlled bursts with refilling tokens
• Leaky Bucket (leaky-bucket feature): Smooth constant output rate
• Sliding Log (sliding-log feature): High precision, stores all timestamps
• Sliding Window (default): Weighted window for balanced accuracy
• Fixed Window (default): Simple counter per time window
• Concurrent (concurrent feature): Limit simultaneous requests
