feat(intercept): 模型审查补充任务上下文与裁决说明 (#124)

审查模型改为接收版本化 JSON：任务描述/目标/操作约束、工作目录、Worker 意图、当前轮输入，以及按 tool_use_id 配对的近期工具执行记录；末尾是完整的 tool_name 与 arguments。

- 任务约束每次审查从数据库重新读取；读取失败或约束超预算转人工。
- 历史只保留唯一配对的执行事实，排除 Agent 自述、未完成请求与平台拒绝反馈。
- 裁决改为 JSON decision(allow/ask/deny) + comment，三种结果均须说明实际操作、成功后果与命中规则。
- 所有模型裁决（含自动放行）保存实际模型输入与 SHA-256 指纹，详情页可展开。
- 对话审批卡片支持展开完整请求、模型输入、裁决与执行结果。
- 修复父目录 lockfile 导致的 Turbopack 根目录误判。

官方默认拦截规则、工具范围与优先级不变。
