fix(cypher): KBDB proxy 指向現役 arcrun-kbdb（舊 fallback kbdb.finally.click 已死）

煙霧測試發現 proxy fallback 寫死舊的 kbdb.finally.click（inkstone 遺留、
回 Missing token），非現役 KBDB。改：
- kbdb-proxy.ts fallback → arcrun-kbdb.uncle6-me.workers.dev（現役、無 auth）
- cypher wrangler.toml [vars] KBDB_BASE_URL 明設現役 URL（self-host fork 覆蓋自己的）

現役 arcrun-kbdb 無 auth middleware，不需 KBDB_INTERNAL_TOKEN。
cli 版本檔 1.3.8→1.3.9（deploy 腳本自動 bump，含 acr kbdb 命令）。

cypher tsc exit 0。
