feat(all): 任务引擎双阶段解耦、僵尸涡旋修复、动态 CPU 配额与前端详情页重构

将 TLUSTY/SYNSPEC 拆为各自独立的 enabled/policy/strategies 阶段，
以策略链自动弹栈取代单级 seed_step 布尔回退；定向修复 2026-08-02
僵尸任务涡旋事故；新增节点并发配额热调；前端详情页从 1412 行巨型
视图拆为薄控制器 + detail 子模块，并补齐工具层与单测。

引擎与调度（task_engine_decoupling_design.md）
- models.rs: 新增 StagePolicy / EngineStageConfig / TaskSpec 阶段字段、
  normalize_compat() 校正旧版在途消息策略链、failed_stage 归因
- scheduler.rs: resolve_dispatchable_chain 派发门控、
  trigger_strategy_fallback 按 failed_stage 精确弹栈；启动期
  force_recompute/skip_converged(默认)/skip_failed 三策略
- db.rs: tasks 表 +7 列持久化阶段配置；终态守卫
  (mark_grid_point_running 仅 pending/queued→running；
  record_task_report 拒绝迟到失败翻黑 converged)；策略弹栈快照

僵尸涡旋修复（runbook-20260802-zombie-vortex-fix.md）
- 全链路跨库活性交叉校验：派发/claim/孤儿回收/回退统一查 MQ 队列活性，
  活则放行、死则清僵尸，结构性消除"每点重复派发"
- stop/重启卫生：清队列同步 delete_tasks_by_ids，杜绝遗留 pending 行
- report_task: 幂等吸收 + 409 区分迟到冗余结果，仅 state_changed 时回退
- MQ: NULL workflow_name 回填 __legacy__、requeue 后迟到上报被 403 竞态修复

动态 CPU 配额（dynamic_cpu_slots_design.md）
- admin.rs: POST /admin/nodes/:id/quota（Option<Option<i32>> 区分
  缺字段/显式 null）；nodes 表 +admin_max_slots
- worker.rs: effective_max_slots = min(admin, physical)，心跳下发原子生效

科学产物保全（tlusty_result_artifacts.md）
- runner.rs: SYNSPEC 启动前快照 fort.12/fort.14 → .bfac/.emflux 防覆盖
- 半失败点(大气收敛+光谱失败)改判 Failed 并写入 note；仅 SYNSPEC
  场景不再恒判失败；撤销归档 LRU 200 上限改为永久保留
- executor.rs: 透传 synspec_params 数值参数（此前固定 None）

前端（dashboard/）
- workflowDetail.js 1412→328 行，拆出 views/detail/{ctx,overview,
  pointsTable,parSets,pointPanel}.js，AbortController 治理监听/请求生命周期
- 删除 wfActions.js，新增 wfEnginePanel.js（双阶段三维配置编辑面板）
- 新增 utils/{errors,format,icons,polling,yamlStage}.js 纯函数模块
- 路由级动态 import 代码分割；节点配额三点菜单 + Modal 管理
- 首次引入 node:test 单测（format/polling/yamlStage/psCache，644 行）
- 系统性补齐 a11y：skip-link、ARIA、Tab 键盘漫游、toast 关闭、退出动画

文档与工具
- 新增 6 篇设计/调研：引擎解耦、动态配额、涡旋 runbook、
  光谱正确性分析、收敛判断、产物归档
- PIPELINE/design/api/database 等协同重写为分布式 C/S 架构口径
- scripts/fetch_results.sh 跨节点产物备份；import_results 按 cno 升序导入
- workflows/sdB_cno.yaml: 新增 tlusty/synspec_stage 配置块，修正 wstart 笔误
