保管：#89/#90/#91 卡在人類閘前的產物，從 session 暫存目錄搶進版控

三樣都做完並實測過，但落地的最後一步是終端機裡等人親手打字的互動閘。它們原本只存在於某個 session 的 scratchpad——那種目錄一關就沒了。 · recipes/gitea_put_file.yaml 出貨線 7 站等它 · recipes/cf_worker_deploy_simple.yaml ⚠️ 只適用無 bindings 的簡單情形（見 #90） · hash-component/ sha256/sha1/md5，已與系統原生指令逐位元核對（.wasm 是 1.3MB 編譯產物，不進版控，README 附重編指令） README 寫了落地指令與各自的注意事項。 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
