HEL-691: deploy S6 visual sweep (feat/hel-685-visual-sweep @ bc24370)

- app.css 删除 8 个无引用 legacy 别名，新增 --id-1..5 身份灰阶实色阶
- 画布去紫罗兰二级 palette（tokens.css 删除，改用全站 token）
- 画布/镜头台/智能体/omni/视频组件硬编码色全部归位 token
- agentPalette 彩色身份色改为显影灰阶 --id 阶；修复 3 处相纸白底白字不可读
- WorkflowLibrary 试运行抽屉焦点还原（异步禁用触发键丢焦）修复
- e2e: fpages/import 色值断言对齐现行 token；新增 hel685 走查脚本
  （1440/1024/390 截图 + 控制台错误 + 减动效 + 键盘焦点 + 对比度探针）；
  pagination 空库自举；fpages 增加逐页控制台错误检查

+"""UI→API converter for ComfyUI workflow JSON (HEL-681 / S2 data layer).

+ComfyUI saves two formats: the editor ("UI") format with ``nodes``/``links``
+arrays, and the API ("prompt") format ``{node_id: {class_type, inputs}}`` the
+product executes. This module converts UI→API offline and deterministically:
+
+* links are rewritten through ``Reroute`` chains and bypassed (mode 4) nodes;
+* packed subgraph instances (frontend ≥1.x ``definitions.subgraphs``) expand
+  into their inner nodes under qualified ids ``<packed>:<inner>`` — the same
+  scheme ComfyUI itself exports;
+* widget values map through, in priority order: the node's serialized input
+  list (entries carrying a ``widget`` marker — authoritative, this corpus's
+  frontend version always writes them), the ``widgets_values_named`` dict,
+  then a generated registry of widget orders learned from the corpus and the
+  repo's ground-truth API exports (``ui_widget_orders``).
+
+Anything that cannot be mapped with certainty is reported as an issue and the
+file is flagged ``needs_confirmation`` — never silently guessed: a wrong
+widget order produces a runnable-looking workflow with swapped seed/steps,
+which is worse than an honest「需人工确认」.
