Sakurasan d5dac5a6fc feat: AutoZero 通用 Agent 框架(从 AutoGo 五阶段拆分完成)
llm(三协议 Provider)/ session(JSONL 持久化)/ tools(Registry、围栏、
builtin、computer)/ cdp(browser)/ skills / mcp / agent(循环、两级压缩、
编排、审批门控)+ 底座 jsonl/textx/execx/diag/scratch/spill/imagecache。

产品装配代码(config 桥接、schedule 工具、memory/plan/retro/prompt)
留在 AutoGo,宿主接入方式见 MIGRATION.md。
