新增: 并行调度+Token预算池+事件协议+前端类型+编译警告清理

- Coordinator.dispatch_with_budget: JoinSet层内并行+层间串行+预算超限降级串行

- TokenBudgetPool: AtomicU64 CAS无锁并发安全,0=不限制

- 4个新事件: AiPlanCreated/AiSubTaskStatusChanged/AiMergeCompleted/AiConflictResolved

- 前端类型: PlanRecord/SubTaskRecord/ConflictRecord/PlanLayerInfo/ConflictInfo

- PlanProgress.vue: 接入真实状态+persona徽章+冲突徽章+i18n

- 编译警告全部清零(audit子模块allow+事件allow+record allow)

- Coordinator测试27个全绿(含4个Token预算+4个并行调度)
