chore(builds): 重編 tier2 成品——把 #108 放進執行檔（出貨路徑 A 的第 0 步）

原始碼修好不等於使用者拿得到：`.worker-builds/` 是安裝器與 `acr update`
實際部署的那份執行檔。本次一併重編，repo_dirty=false、repo_head=b223a698。

  arcrun-cypher-executor  sha256=e0026a23792f  source=b223a698 ← #108
  arcrun-kbdb             sha256=9c6d41895d78  source=f87d0e92（未變）
  arcrun-http-request     sha256=9a9dcb71879a  source=1e85dfb4（未變）
  arcrun-code             sha256=285a7406ec69  source=621cb8d9（未變）
  arcrun-mcp              sha256=3ebc0d441bc0  source=10d150ac（未變）

其餘四顆的 js 位元組有變是 esbuild 版本/相依重裝造成的重編，source commit 未動。
本次起這條路徑多一道閘：編成品前先跑租戶來源檢查，違規直接「建置中止」
（見同 PR 的 scripts/build-worker-artifacts.mjs）——實跑輸出貼在 PR。
