Implements a complete alias system allowing players to create command shortcuts. Aliases are expanded during dispatch with a recursion guard (max 10 levels). Changes: - Add aliases field to Player dataclass (dict[str, str]) - Add player_aliases table to database schema - Add save_aliases() and load_aliases() persistence functions - Add alias/unalias commands with built-in command protection - Integrate alias expansion into dispatch() before command resolution - Add comprehensive test coverage for all features
