- Standardize all handlers to signature: (query, user_id, player, data=None)
- Replace 125-line if/elif chain with HANDLER_MAP dictionary
- Reduce router code by 90 lines (72% reduction)
- Add HANDLER_MAP registry for cleaner organization
- Enable future auto-discovery and decorator patterns
- Maintain full backward compatibility
- Document changes in HANDLER_REFACTORING_V2.md
Benefits:
- O(1) handler lookup vs O(n) if/elif chain
- Add new handlers by just updating the map
- Consistent signature makes code easier to understand
- Opens doors for middleware and hooks
