feat(playable): 首个 Mac 联网内测版 STB-01 soak 工具与发布状态文档

- 新增 script/playable_soak.sh：先做 soak 配置/资源校验，无 --allow-gameplay
  只校验不启动客户端；N(>=10) 次独立正常退出运行 + 墙钟 soak，失败即停止后续
  运行并记 BLOCKED；写本批次 release-manifest.json 后聚合
- run_client_gate.sh：确认的故障代理对所有 suite 启动（共享场景的退出运行也经代理）；
  soak 超时下限只约束 soak 客户端（validate_soak 增加 soak_client 参数）
- 新增本地 127.0.0.1 故障代理、RSS 采样/内存判定、窗口/指标/流程模块及其测试
- forest_mob_render_test 输出 PASS/FAIL 标记，供 rendering_batch_test.sh 识别
- 新增 docs/FIRST-MAC-PLAYABLE-STATUS.md：如实记录 PASS/BLOCKED、已知问题与环境需求
- .gitignore 排除本地场景配置、凭据文件与运行输出

离线回归：rendering_batch_test.sh failures=0，playable_gate_test.sh PASS，
node 夹具测试 PASS。未联网运行，未重建候选包。
