Release - FixClaw | OpenClaw 故障排除知识库

[子代理不再继承调用者账户] - Agents/channels: route cross-agent subagent spawns through the target agent's bound channel account while preserving peer and workspace/role-scoped bindings, so child sessions no longer inherit the caller's account in shared rooms, workspaces, or multi-account setups.

[保留会话令牌总数避免提供商元数据缺失时回退到未知/0%] - Agents/status: preserve carried-forward session token totals for providers that omit usage metadata, so `/status` and `openclaw sessions` keep showing the last known context usage instead of dropping back to unknown/0%.

[按目标会话划分嵌套代理工作，避免长运行阻塞网关其他会话] - Agents/nested lanes: scope nested agent work per target session so a long-running nested run on one session no longer head-of-line blocks unrelated sessions across the gateway.

[修复流式请求上下文使用量报告] - Agents/openai-completions: always send `stream_options.include_usage` on streaming requests, so local and custom OpenAI-compatible backends report real context usage instead of showing 0%.
