重构: ARC-05 project.ts 上帝 store 拆分(4 子 store+barrel 兼容零改动)

拆 stores/project/{state,projects,tasks,ideas,workflow}.ts 四领域子 store(共享 state 单例 reactive 引用一致);越层 invoke approve_human_approval/cancel_workflow_node 下沉 src/api/workflow.ts;project.ts 改 barrel 组合器(实例化四子 store+re-export 所有成员,useProjectStore 单例+ProjectStore 类型保留)。所有 view(App/Dashboard/Ideas/ProjectDetail/Projects/Tasks/ToolCard)import '../stores/project' 零改动。行为零变化(含 CR-11⑪ approveHumanApproval 签名+B-34 snake_case)。批6,vue-tsc 0
