feat(engine): 添加运行时上下文支持并重构工具迭代限制
添加 RuntimeContext 类用于捕获模型运行时的日期时间信息， 包括UTC时间、本地时间和时区信息，并在系统提示中显示这些信息。 同时增加最大上下文消息数和工具迭代次数的配置选项， 将验证服务从引擎加载器中移除，并更新相关的数据结构和接口。 BREAKING CHANGE: 移除了验证服务，相关字段被替换为证据状态和接受状态。 - 添加 RuntimeContext 类和相关渲染方法 - 增加 max_context_messages 和 max_tool_iterations 配置 - 移除 ValidationService 相关代码 - 更新消息记录中的验证状态字段 - 添加原始工具调用检测和回退处理

<h2>项目是干嘛的</h2>
|
||||
<p>
|
||||
Beaver 后端是一个面向用户任务的 agent runtime。它接收来自 Web、WebSocket、CLI、Gateway、Cron 或 MCP 的请求，
|
||||
用 Main Agent 判断这是不是一个需要跟踪的 Task；简单问题直接回复，复杂任务进入 Task mode。Task mode 会规划单 agent
|
||||
或 team 执行，运行统一的 <code>AgentLoop</code>，选择技能和工具，调用模型，记录事实证据，并等待用户接受、修改或放弃。
|
||||
只有用户接受后的 Task evidence 才会沉淀为可学习的 skill 候选。

<h2>最关键的架构判断</h2>
|
||||
<p>
|
||||
主 agent、team node、sub-agent 都不各自实现一套 runtime；它们最后都回到同一个 <code>beaver.engine.AgentLoop</code>。
|
||||
因此后续修改时要优先确认：入口层是不是薄的，服务层是不是只编排，真正 tool loop / prompt / provider / session 逻辑是不是仍在 engine 内收口。

<h3>定时 Task 路径存在明显变量错误</h3>
|
||||
<p>
|
||||
<code>AgentService.run_scheduled_task()</code> 末尾更新 assistant event payload 时引用了 <code>job.id</code>、<code>run.scheduled_run_id</code>、<code>job.name</code>，
|
||||
但该函数参数只有 <code>cron_job_id</code>、<code>cron_job_name</code>、<code>scheduled_run_id</code>。这条路径如果执行到这里会触发 <code>NameError</code>。

<h3>权限层还没有真正成为执行闸门</h3>
|
||||
<p>
|
||||
<code>permissions</code> 目录为空骨架，实际保护分散在工具实现和路径校验里。若后续开放 terminal、filesystem、MCP sensitive tools，需要统一执行前 policy。

<h3>Web auth 是本地单用户风格</h3>
|
||||
<p>
|
||||
本地 auth 文件以 username/password 字段读写，使用 token/handoff code 做前端会话。若目标是多用户或公网后端，需要重新评估密码存储、token 生命周期和权限边界。

<h3>Skill eval 目前偏轻量启发式</h3>
|
||||
<p>
|
||||
<code>SkillDraftEvaluator</code> 基于历史 accepted task evidence 和草稿长度/内容做 bounded report，不是真正 replay。它只属于 skill draft 治理，不属于 Task runtime。

<h3>接口层过大</h3>
|
||||
<p>
|
||||
<code>interfaces/web/app.py</code> 同时承载 app factory、lifespan、auth、provider config、sessions、files、agents、MCP、Outlook、skills、cron、chat、helper functions。
|
||||
后续修改时容易产生跨功能回归。

<h3>已经落地的稳定点</h3>
|

<p>
|

<span class="ok">可依赖：</span>统一 <code>AgentLoop</code>、session event stream、Task evidence/acceptance 状态、team graph v1、skill lifecycle gates、MCP wrapper、workspace path containment。
