本次围绕 Eino P0 能力做了配置落地与缺陷修复：启用 plantask 结构化任务板、checkpoint 崩溃续跑、模型调用重试与 session 输出键；修复 plantask 在第二次 TaskCreate 时因路径不兼容导致 .highwatermark 读失败的问题；补齐 summarization 触发后 conversation_artifacts/.../transcript.txt 未写入的缺口，并按最佳实践瘦身 transcript——完整保留 user/assistant/tool 轮次与项目黑板等动态注入，省略工具索引、固定 system 与 Skills 模板等静态内容，供压缩后 read_file 查阅技术细节。
This update lands the Eino P0 stack—plantask task boards, checkpoint resume, ChatModel retries, and session output keys—and fixes a plantask path bug that broke TaskCreate after the first task. It also adds summarization transcript persistence under conversation_artifacts, with best-practice filtering: full user/assistant/tool history plus dynamic project blackboard, while omitting static system prompts, tool indexes, and Skills boilerplate so models can recover technical details via read_file after context compression.
