feat(km-wiki-ingest): 重做成跑在 cypher 上的 workflow(走 cypher binding,汰換 service-binding drainer,D28)

把知識庫 ingest 從 standalone drainer(誤用 Service Bindings)重表達為 cypher workflow:

- workflow.yaml(Phase 0 cron drain):watch_cron→load_cursor→list_cards→pick_card(code)
  →fetch_card→parse_card(code)→upsert_entry→save_cursor→post_envelopes→post_one_envelope。
  線性 pipe,跨-worker 全走 cypher binding(零件節點),零 service binding。
- workflow.delta.yaml(Gitea webhook 穩態):collect_changed(code)→foreach card→fetch/parse/upsert/foreach envelope。
- code/kbdb/graph 接法:code=canonical `code` 零件(arcrun-code);kbdb/graph=http_request 零件打
  /entries/ingest、/triplets/ingest(server 端冪等);Gitea=http_request。
- 平台端最小補丁(各需 gated 部署):
  1) cypher-executor component-loader:WASM_HTTP_RUNNER_IDS 加 'code'(canonical→arcrun-code,cypher binding 正解)。
  2) kbdb base:POST /entries/ingest(page_name+content_hash 冪等 upsert,對稱 graph /triplets/ingest;
     因 flow DSL 無資料條件分支,把 create/patch/skip 冪等推到 server 端)。
- drainer/DEPRECATED.md:標舊 standalone worker 退役計畫(新版穩定後 wrangler delete)。
- DEPLOY.md:部署順序、cron/webhook 掛法、subdomain 對齊、驗收與退役。

本輪不部署(待總管/leo 審架構)。

Phase 0 限速 draincron 每 tick 只處理「一張卡」→ 機械解析成 entry + triplet envelope

Phase 0 限速 draincron 每 tick 一卡)——**跑在 cypher-executor 上的 workflow,全程走 cypher binding
零 Service Bindings**D28)。來源=Gitea repo 的 system-dev/wiki/cards/**/*.md(人工精耕卡,無 LLM
卡片 → 通用 `code` 零件機械解析成 entry + triplet envelope → 冪等寫 KBDB base/entries/ingest
與 graph/triplets/ingest)。反覆跑直到全庫 drain 完;穩態改走 webhook(見 workflow.delta.yaml)。
# ── 為什麼「一 tick 一卡」=根治 07_01 的 Too many subrequests ──
# graph worker 處理一次 POST /triplets/ingest 的 subrequest = 7 + 4*N_triplets + M_nodes + D_deprecated
# 07_01 炸點:單一 envelope 吞整檔 N=11,M=10 → 61 > 50CF bundled 上限)→ 半殘。
# 對策:① 一卡一 tick(天然小批,notes 卡 ~N4/M5 → est 28~33,穩壓 50 下)
# ② code 節點的內聯解析會自動把超大卡以 source_uri anchor 分段(每段獨立冪等)。
# ⟹ 任何單一 graph 呼叫都不會再破頂。
# ═══════════════════════════════════════════════════════════════════════════
# 架構(D28 訂正):這**不是** standalone drainer worker,是 cypher workflow
# - 跨-worker 呼叫一律走 **cypher binding**=把每個外部呼叫表達成一個「零件節點」,
# 由 cypher-executor 的 component-loader 解析執行。**不用 Service Bindings**
# service binding 只准「零件內部把幾個 wasm 綁成複合零件」的零件等級,見 D28)。
# - code/kbdb/graph 的接法(皆 cypher binding,非 service binding):
# code → canonical 零件 `code`arcrun-codeQuickJS 沙箱;純函式解析)
# kbdb → `http_request` 零件打 {{kbdb_url}}/entries/ingestbase 的 server 端冪等 upsert
# graph → `http_request` 零件打 {{graph_url}}/triplets/ingestgraph 的 server 端 per-source 冪等)
# Gitea → `http_request` 零件(外部 API,本就走公網)
# - 觸發:cron 零件節點(cypher scheduled() 每分鐘掃 cron-idx 觸發本 workflow)。
#
# ⚠️ 部署前置(見 DEPLOY.md):
# 1) cypher-executor 需能解析 `code` 零件 —— 目前 component-loader 的 WASM_HTTP_RUNNER_IDS
# 白名單未含 `code`(本分支已補 1 行;或改用 code 的 workers.dev 完整 URL 當 component)。
# 2) KBDB base 需有 POST /entries/ingestpage_name+content_hash 冪等 upsert)——本分支已加,
# 與 graph /triplets/ingest 對稱。若不部署它:改用「lookup→decide→create/patch」多節點版(較繁,
# 且 flow DSL 無資料條件分支,需靠 ON_SUCCESS/ON_FAIL 兩路 hack,故不建議)。
#
# ── 為什麼「一 tick 一卡」=根治 07_01 的 Too many subrequests(同原設計,不變)──
# graph 處理一次 /triplets/ingest 的 subrequest = 7 + 4*N_triplets + M_nodes + D_deprecated
# 07_01 炸點 N=11,M=10 → 61 > 50。對策:一卡一 tick(天然小批)+ code 節點超大卡以 source_uri anchor 分段。
