Unify all handler signatures and simplify router
- 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
