feat: Add standalone agent CLI command

- Add 'local-ai agent run' command to run agents in standalone mode
- Accept agent name as required argument
- Accept optional JSON configuration file path
- Create agent state directory under data path
- Load agent configuration from file if provided
- Use default configuration with agent name if no file provided
- Integrate AgentCMD into main CLI struct
