Leo fdb7a67484 feat(ingest-hash-trigger): collector R2 content-addressed 原稿上傳(SDD task 3)
- collector upload 子命令=scan+把 added/modified 原稿傳 R2(CF REST API
  Bearer token,key=raw/<sha256hex>,對齊 collector-trigger.v1 的 r2_key)
- 冪等:存在檢查命中=skipped_exists 不 PUT;CF API objects 端點不支援
  HEAD(live 實測 405)→ 改 GET+Range: bytes=0-0
- 完整性:上傳前重算 hash 核對 key,不符=failed 不上傳
- 失敗語意:failed → exit 1,ingested_hash 不動=下輪自動重試;
  回寫鉤子 Manifest.MarkIngested 留給 task 4
- 設定只走環境變數 CF_ACCOUNT_ID/CF_API_TOKEN/R2_BUCKET,不落 repo
- go test 14/14 綠(httptest mock 對齊真 API:HEAD 405);live e2e 全通
  (arcrun-rag-raw-demo:真上傳→重傳 no-op→下載 diff 一致+sha256==key)

// collector — hash 差異偵測 collectorSDD ingest-hash-triggerGo 版)。
//
// 用法:
//
// collector scan --root <知識資料夾> --manifest <manifest.json 路徑> \
// [--max-removed-ratio 0.4] [--dry-run]
// collector upload --root <知識資料夾> --manifest <manifest.json 路徑> \
// [--max-removed-ratio 0.4] [--dry-run]
//
// scan:走訪 root、對照 manifest、把事件(符合 schemas/collector-trigger.v1.schema.json
// 以 JSON 輸出到 stdout,並更新 manifest--dry-run 不寫)。
//
// uploadtask 3)=scan+把 added/modified 的原稿上傳 R2content-addressed
// key=raw/<sha256hex>design §4)。設定走環境變數 CF_ACCOUNT_ID / CF_API_TOKEN /
// R2_BUCKET(絕不落 repo);--dry-run 只列出會上傳的 keyplanned),不碰網路不寫 manifest。
// 任一上傳失敗=exit 1manifest 照存:content_hash 反映現況、ingested_hash 不動=可重試)。
//
// daemon 常駐(launchd/打 named-webhook 觸發 ingest=之後的 taskSDD task 4、產品化段)。
