feat: /goal命令能力支持，参考codex实现 (#1261)

* feat: /goal命令能力支持，参考codex实现

* fix: 修复promp和提示词不一致的问题

* fix: 修复 goal 功能多项 AI 审查问题

- prompt 中 update 行为描述与运行时不一致（no-op → error）
- src/commands/goal/ 使用相对路径导入，改为 src/* 别名
- /goal 命令标记 bridgeSafe 但含交互式对话框，改为 false
- useGoalContinuation 中 origin 使用 as unknown as string 强转，改为直接传字符串
- ResumeConversation 路径缺少 goal hydration，补齐恢复逻辑
- onCancel 在非查询状态下误暂停 goal，加 queryGuard 守卫
- resumeGoal 允许从终态恢复，收紧为仅允许 paused 状态
- buildGoalContextBlock 生成畸形 XML 属性，改为合法 budget 属性

* fix: 修复剩余AI审查的问题

* fix: 防止goal状态丢失

* fix: 修复Biome规范错误问题

* fix: 修复部分情况下goal无法启动的问题

* fix: 增加断网后状态默认设置为PAUSE机制、完成暂停-恢复状态切换，且正常进行前端渲染。设置达到max turn后处理逻辑。

* fix: 修复终端异常断开情况，resume续跑；修复用户消息排队信息被goal输出信息覆盖的问题。

* fix: apply biome formatting to pass CI lint check
