feat(kernel): add internal ZCLAW kernel integration with Tauri

Phase 1-3 of independence architecture:
- zclaw-types: Add ToolDefinition, ToolResult, KernelConfig, ModelConfig
- zclaw-kernel: Fix AgentInfo provider field, export config module
- desktop: Add kernel_commands for internal kernel access
- Add AgentId FromStr implementation for parsing

New Tauri commands:
- kernel_init, kernel_status, kernel_shutdown
- agent_create, agent_list, agent_get, agent_delete
- agent_chat
