是否可以增加上几分消耗的限制设定

### Problem Statement

当前的整个仓库想做 scan 或 review，执行的积分消耗非常的恐怖，比如使用的 阿里云 token plan 对项目做扫描，好几万的积分给清空任务也没执行完（肉疼），非常需要是否可以增加扫描限制，比如选择模型后设置超过1w积分自动中断扫描或二次提醒是否继续的功能？

### Proposed Solution

建议增加积分限制功能避免过多消耗积分

### Alternatives Considered

_No response_

### Affected Area

Review Agent / LLM interaction, CLI / Commands

### Additional Context

_No response_

Start at the Review Agent / LLM interaction and CLI / Commands entry points, then trace how scan and review consumption is tracked. Done should include a configurable point limit and either automatic interruption or a confirmation prompt when the limit is reached.
