Integrates the Editor class into the MUD server's shell loop, allowing players to enter and use the text editor from the game. Changes: - Add editor field to Player dataclass - Modify shell input loop to check player mode and route to editor - Add edit command to enter editor mode from normal mode - Use inp (not command.strip()) for editor to preserve indentation - Show line-numbered prompt in editor mode - Pop mode and clear editor when done=True - Add comprehensive integration tests - Fix test isolation issue in test_movement_updates_position |

How it works
The world is a toroidal 2D grid of terrain tiles, not discrete rooms. Players see a viewport centered on their position. Terrain types have mechanics — shallow water slows you, mountains block you, forests hide you.
Combat is timing-based with telegraphed moves and cooldown management, not turn-based.
The server runs a tick-based async game loop alongside the telnet server. SQLite handles persistence. Session mode stacks filter what reaches the player depending on context (exploring, fighting, composing, solving puzzles).
