修复: aichat P0 三项（AR-2 新建对话守卫 + AR-3 审批卡片可读化 + AR-4 create_project 双审）

- AR-2 ai_conversation_create 加 generating 守卫（clear 前，防审批态新建清空 session 致 generating 永不复位卡死）
- AR-3 audit.rs build_approval_reason 按 9 工具特化拼对象名（id/field/path/title/name）+ ToolCard resultSummary 补 restore/purge case + ARG_LABEL_MAP id 加友好标签 + i18n 双语补 4 key
- AR-4 create_project schema 加 path/stack + handler 有 path 时合并绑定（spawn_blocking 探测栈，复用 bind_directory 逻辑，消除双审双 API）
- cargo check / vue-tsc 0 error
- 审查 boundary 全误判（并行同工作区 git diff 污染），主代理独立核查三任务全正确
