feat(mcp): Implement MCP Player system for headless AI control

- Add MCPPlayerManager for multi-session AI player management
- Add Player::InitializeForBot() for minimal bot player initialization
- Add AraxiaCore hook system for World::Update callbacks
- Add packet capture callback for headless WorldSession
- Add 14 MCP tools for session/player control

Key fixes:
- Async login/logout to ensure map operations run on world thread
- Manual player cleanup to avoid RemoveFromWorld() hangs
- Null socket handling in WorldSession for headless sessions
- Safe shutdown without mutex issues during static destruction

Test scripts:
- test_mcp_player.sh - Interactive bash test
- test_mcp_integration.py - Python integration tests

Files:
- src/araxiaonline/mcp/MCPPlayerManager.{h,cpp}
- src/araxiaonline/mcp/MCPPlayerTools.cpp
- src/araxiaonline/AraxiaCore.{h,cpp}
- Modified: Player.{h,cpp}, WorldSession.{h,cpp}, World.cpp
