feat(portable): 内网/局域网可用性工具包 + 启动绕代理 (v2.1.10)

便携版在内网/离线/受控浏览器环境下"配不上、用不了、查不清"的三个痛点工具化，
Win + Mac 双端，纯 Node 零依赖脚本，中文提示由 node 打印（.bat 保持纯 ASCII，
.command 保持 LF），三端真机验证（本机 Win / Mac mini / 客户机 pc-7512）。

新增工具:
- lib/intranet-check.mjs (+ Windows-IntranetFix.bat / Mac-IntranetFix.command)
  一键体检: 代理env + 直连可达 + 真发一条对话，分清"网络不通 vs 配置错"。
- lib/setup-local-model.mjs (+ Windows-LocalModel.bat / Mac-LocalModel.command)
  纯命令行配 Ollama / newapi 并当场实测，绕开打不开的 Control UI；写前自动备份+merge。
- lib/resolve-no-proxy.mjs 接入 Windows-Start.bat / Mac-Start.command:
  把配置里的模型 host 写进 NO_PROXY，避免系统代理劫持内网模型请求
  (OpenClaw 自身只 bypass loopback CDP，不管模型 host)。
- OpenClaw-Doctor.bat / Mac-OpenClaw-Doctor.command: 官方 doctor 的隔离进阶入口
  (只读、非交互；doctor 实跑慢且 TTY-only，故不进客户一键流程)。

测试: tests/windows-launchers.test.mjs 新增回归
- 客户面 .bat 必须纯 ASCII (UTF-8 中文会被 GBK cmd 读乱，报 usebackq 不是命令)
- macOS .command 必须 LF-only (CRLF 触发 bad interpreter: /bin/bash^M)
