Feat: Hermes PC-Zugriff via MCP (executor + mcp_pc)

- mcp/mcp_pc.py: MCP-Server der PC-Tools an den Executor proxied
  (pc_shell, pc_screenshot, pc_type, pc_key, pc_open, pc_status)
- client/hermes-pc/executor.py: FastAPI auf Port 7777 (Daemon-Reg entfernt)
- client/hermes-pc/start.bat, install.bat, requirements.txt
- client/hermes-voice/agent_client.py, main.py: agent_client integration
