Claude 5fc7277c3c refactor(mcp): u6u_* tool 全面 rename 為 arcrun_* + 前綴收斂單一來源
零 u6u 洩漏(leo 要求 1):connector tool 清單只剩 arcrun_*,並移除壞掉/
重複的 u6u_ workflow tool(deploy/execute/get/list_workflows 由 arcrun_
push/run/get/list_workflows 取代);MCP server name 也由 u6u-mcp-server
改 arcrun-mcp-server。

前綴單一真相源(leo 要求 2):新增 mcp/src/brand.ts(TOOL_PREFIX + toolName()
helper),所有 server.tool() 註冊一律走 toolName("suffix"),前綴不再明碼散寫。
未來 rebrand 只改 brand.ts 一行。

- 12 個獨有能力 tool rename(component/tag/gui/search_workflows)
- 4 個重複/壞掉 tool 移除
- inter-tool hint、描述字串、註解內 u6u_ 名字全數更新
- tsc exit 0;vitest 19/19 綠

/**
* arcrun_search_workflows — 用自然語言找現成工作流(workflow-discovery R2
*
* 北極星入口:AI 先查「有沒有現成工作流能做這件事」→ 找到就執行,別重造。
* 呼叫 cypher GET /workflows/search → 轉發 KBDB /entries/searchentry_type=workflow + 本租戶)。
* 優先語意搜尋;KBDB 未開 Vectorize → 自動降級關鍵字 + 回 capability_hint(不假裝語義)。
*
* 薄殼(rule 07):只做參數轉換 + 呼叫 + 格式化,零業務邏輯。形態對齊 arcrun_search_components。
* flag 安全:AI 收到意圖時主動 call 一次,無輪詢/排程。
