Implement AI player spawning near human player

Objective

Create AI opponent system that spawns near human players to provide immediate challenge for MVP single-player experience.

Requirements

• Proximity Detection: Spawn AI when human player is detected
• Base Placement: Place AI base "a close walk" from human player
• AI Initialization: Set up AI player with same starting resources
• Same Rules: AI follows identical game rules as human players

Technical Details

• Detect when human player connects and is placed
• Calculate optimal AI base placement near player
• Initialize AI player state and resources
• Set up AI decision-making loop
• Ensure AI uses same building/unit systems
• Handle AI persistence until defeated

Acceptance Criteria

• AI spawns automatically when human joins
• AI base is placed near but not too close to human
• AI starts with same resources as human player
• AI persists until defeated or human disconnects
• AI follows same game rules and mechanics
