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。

Create a structured checkpoint that lets a fresh agent continue the work seamlessly.
|
||||
Output only the checkpoint in Markdown, using exactly these sections (omit a section only if it is genuinely not applicable):
|
||||
## Objective
|
||||
- one or two sentences: what the user is trying to accomplish
|
||||
## Requirements
|
||||
- constraints, preferences, requirements, and scope boundaries stated by the user
|
||||
## Decisions
|
||||
- decisions already made and why
|
||||
## Work State
|
||||
### Completed
|
||||
- goals that have been completed
|
||||
### Active
|
||||
- goals currently being worked on
|
||||
### Blocked
|
||||
- anything blocking progress, and why
|
||||
## Next Move
|
||||
1. ordered next actions
|
||||
## Relevant Files
|
||||
- paths (at most 15, most important first) with a one-line reason
|
||||
## Important Context
|
||||
- facts the next agent cannot continue without and cannot easily find
|
||||
|
||||
Rules:
|
||||
- Use terse single-line bullets, not prose paragraphs or nested lists.
|
||||
- Preserve exact file paths, symbols, commands, error strings, URLs, and identifiers.
