fix: MCP server starts after 3rd frame to avoid blocking Vulkan init

Browse Source 
- MCP server (Kestrel) launched on background thread after 3 frames
  to avoid conflicting with Vulkan/SDL3 initialization
- --mcp-port 0 (default) = disabled, scene works as before
- --mcp-port 5000 = MCP starts after 3rd frame
- Reduced extra balls from 30 to 10 for stability
- Engine.AI/McpEngineServerHost reverted to original (no WebApplicationOptions)
