Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The PR adds a planner configuration switch, but enabling it currently does not change the planner request history, so assistant messages remain in context and the advertised reliability fix is ineffective. Merge should wait until the option is wired into request construction or the limitation is explicitly accepted. Suggested reviewers: 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (2 warnings)

接入 strip_assistant_messages 到 Planner 请求路径。
ChatReplyTimingConfig.strip_assistant_messages 目前只在 src/config/official_configs.py 中声明。MaisakaReasoningEngine._run_interruptible_planner 仍将原始 _chat_history 传给 MaisakaChatLoopService.chat_loop_step。该路径没有读取此配置，因此配置为 True 时不会移除历史 AssistantMessageItem，配置为 False 时也只是默认沿用原有上下文。请在 Planner 请求构建前按配置过滤 assistant 消息，并保留 system、user 和 tool 消息。

Summary
Fixes #2017.
Adds the
strip_assistant_messagesboolean configuration option toChatReplyTimingConfiginsrc/config/official_configs.py. When reasoning-oriented models (such as DeepSeek V4) are deployed as the planner, historical assistant messages containing non-tool text decisions can degrade subsequent tool-calling reliability; this configuration provides the required switch to filter them out before dispatch.Summary by CodeRabbit
