feat: implement toolify function calling via VM sandbox prompt

Browse Source 
- Add virtual machine sandbox prompt injection for tool calls
- Parse <vm_write> and <vm_exec> tags from model response
- Handle tool_result to avoid infinite loops
- Extract tool_result content for model to respond
- Optimize streaming with batch flush
- Remove unused MCP and tools modules
