arcrun — AI workflow execution engine (clean history)

Self-hosted 開源:WASM 零件 + recipe + cypher-executor,跑在你自己的 Cloudflare。

此為重建的乾淨歷史起點(移除曾誤 commit 的 GCP SA 金鑰,舊歷史保留在
richblack/arcrun 與本地 backup 分支)。含:
- acr init --self-hosted installer(建 KV/R2 + codeload 拉預編譯 wasm + wrangler deploy + seed recipe)
- recipe push 把關(資料外流提醒 + 打通檢查)
- 19 個正當零件預編譯 wasm(claude_api/km_writer/kbdb_upsert_block 排除:違反 DECISIONS §1)
- CLI / cypher-executor / registry / 完整 SDD

* - 本檔**不做**任何 credential 解密 / template 展開 / JWT 簽章
* - 那些全部在 auth primitive WASM 零件內執行(透過 host function `crypto_decrypt` 等)
* - 本檔只做「查 recipe 決定走哪個 primitive Worker」+「HTTP fetch 取回注入結果」
*
* 目前階段接上 `auth_static_key` + `auth_service_account` + `auth_oauth2`,
* Phase 4 剩 `auth_mtls`mTLS handshake 在 Worker runtime 層)。
*
* 執行時機:graph-executor 在節點 runner 執行前呼叫,取回的 ctx 會:
* 1. 先試本 dispatcher(命中才 return enriched ctx)
* 2. 沒命中 fallback 到 `injectCredentials`(Phase 1.9 才刪除)
