- 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
- Add type hints to create_progress_bar() and format_stat_bar()
- Add type hints to admin_only() decorator and is_admin()
- Use f-strings for logging (Python 3.11 compatible)
- Improves code readability and IDE support
- Update combat_handlers.py to show visual enemy and player HP bars
- Update action_handlers.py combat encounters with progress bars
- Update combat.py attack results with visual HP displays
- Add UI_EXAMPLES.md with before/after comparisons
- All combat displays now use format_stat_bar() for consistency
