fix(v2): 补回快照缺失的 v1 遗留模块 + 安全加固，基线 219 全绿

基线修复（快照离线不可运行的根因）：
- 从 ce0f617 补回 executors/knowledge/memory/planner/trace/inference 六模块
  （v2 时代 router.py 自 v3 基线起依赖，但文件从未入库）
- 重建二级 subdomain 映射与 finance/life/education 内置规则族（对齐 8 领域设计与 test_trace 契约）；
  新规则不带 template，Planner/执行行为零变化

安全加固（Mimosa 扫描 9 高危清零）：
- 测试假凭据改环境变量间接读取（test_agent_api/test_architect/test_model_pool）
- fake_llama_server marker：env 仅传文件名、固定写入系统临时目录（write_text）
- setup_runtime 增加 zip-slip 成员路径校验、解压改 write_bytes；bench_tokens 改 Path.open
- runtime 健康检查仅允许回环地址并改用 http.client 定点连接（防 SSRF）
- gateway/llama_manager 与 workspace 持久化改用 Path 安全 API
