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

+I'll design Arcrun as a cohesive 5-screen system. Let me plan and build this as an interactive prototype with all screens navigable.

+
+Let me plan the architecture. I'll build a single HTML file with React, using multiple JSX component files, with screen navigation via state.
+
+Design system note: I'll use Inter, electric indigo #6366F1 primary, #0F0F0F bg, #1A1A1A cards, with subtle indigo→violet gradients on CTAs. Dark, minimal, developer-focused. "Arcrun" wordmark will be original — a stylized "↯" or arc mark paired with the name.
+
+Let me start building.

+Built **Arcrun** as a cohesive 5-screen dark-mode prototype — Landing, Auth, API Keys, Dashboard, and Workflow Viewer — all navigable via the floating screen switcher at the bottom.
+
+**Highlights**
+- **Landing** — hero with grid/glow bg, two-path split (developer terminal w/ npm·pip·bun tabs + Claude-style chat preview showing an Arcrun tool call)
+- **Auth** — centered card, Sign in / Sign up tabs, GitHub + Google OAuth, email + password
+- **API Keys** — first-time key callout with copy + hide-again warning, full keys table with live status toggles
+- **Dashboard** — sidebar shell, 3-col apps grid (+ empty-state card), workflows table below
+- **Workflow Viewer** — full-bleed dark canvas, 8 connected nodes with left-to-right bezier arrows, selectable with detail panel (I/O schema, editable triplet config for the AI node), minimap + zoom controls, prominent "Edit in Claude" CTA
+
+Screen state persists in localStorage so reloads land you where you were.
