Record a new timestamp and perform cleanup if needed

This function adds a new timestamp to the collection and optionally performs cleanup of old timestamps to maintain memory efficiency.

Arguments

• timestamps - Mutable reference to a vector of timestamps
• timestamp - The new timestamp to record
• window_duration - Duration of the rate limiting window
• max_capacity - Optional maximum capacity for the timestamp vector
• auto_cleanup - Whether to automatically cleanup old timestamps

Returns

The number of timestamps that were cleaned up (if any)
