Enhance the Redis buffer system to support dedicated queue routing for different models, improving performance isolation and reducing buffer processing contention across high-volume models. Key improvements: - Add PendingBufferRouter for per-model queue assignment - Implement RedisBufferRouter with customizable queue functions - Extract model metadata from Redis keys for routing decisions - Add comprehensive test coverage for custom queue assignments This optimization allows critical models like Group to use dedicated processing queues while maintaining backward compatibility for models without custom queue assignments. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

Pull Request Overview
This PR optimizes the Redis buffer system by implementing a router-based approach that allows different models to use dedicated queues for processing buffer increments. This prevents backlog issues with one model from affecting others.
- Introduces
RedisBufferRouterandPendingBufferRouterclasses to manage model-specific buffer routing - Replaces single shared
PendingBufferwith multiple model-specific buffers - Adds queue assignment functionality for models to use dedicated processing queues

[nitpick] Use {} instead of dict() for better performance and readability when creating empty dictionaries.
