batch step3/4/5/6 全量重生（Arcrun@eefbed9）：步驟5 引擎條件邊＋recipe 三層

來源＝Arcrun `batch/step3456-20260801`（eefbed9）＝step3 最前緣（已含 step4+step6＋
t158-t162）合入 step5。**先合流再打包**（bundle 是 worker 粒度，三步同一顆 cypher，
分開建會讓 stage 只拿到一步——08-01 那個坑）。

cypher 產物指紋（步驟5 新增，實查）：
  ON_BRANCH 13／ON_TRUE 9／ON_FALSE 11／branch_hint 4
  body_template 8／response_map 8／binding_name 4
步驟3/4/6 迴歸指紋（不得歸零，實查全在）：
  trySubstitution 3／input_schema 6／not_found 5／suggestion 2／success_rate 4／bundle_version 1
mcp 教材世代更新：「引擎不支援條件分支」字串歸 0，換成三型分支寫法＋branch_hint 指路。

保留未動（本建置腳本不產這兩顆）：tier1/code、tier2/ui、daemon 段（仍 v0.15.0，
這批不含新小幫手，leo 不必重下載）。core 條目維持 24。

順手清掉既存污染：上一版 staging 的 tier1/*/index.js 內含建置機器的絕對路徑
（`/Users/youlinhsieh/...`，19 檔命中）＝前次以 symlink node_modules 打包的殘留；
本次改為實體複製 node_modules 後重建，路徑回正常相對形式，命中歸 0。
⚠️ 僅 `tier1/code/index.js` 仍有（該檔本腳本不重建、本次未動），留給產它的那條線處理。
