Feature Request: Support for Recent Models in Copilot CLI

### Describe the feature or problem you'd like to solve

Add functionality in Copilot CLI to list and quickly access recently used models, including version details, so users can switch or re‑use them more efficiently.

### Proposed solution

Add functionality in Copilot CLI to list and quickly access recently used models, including version details, so users can switch or re‑use them more efficiently.

**Motivation**
Currently, users need to manually specify model names or versions each time. This can be cumbersome when working across multiple projects or testing different releases. Having a “recent models” feature would streamline workflows and reduce repetitive typing.

**Proposed Solution**

- Introduce a copilot models recent command to display a list of recently used models.

- Show metadata such as model name, version, and last used timestamp.

- Allow quick switching with copilot use or copilot use .

- Optionally support a configurable limit (e.g., last 5 or 10 models).

该 issue 未指定文件、测试或入口点。首先定位 Copilot CLI 中现有的模型选择命令处理逻辑，以及模型使用情况的记录方式。完成标准是实现最近使用模型列表、模型元数据、快速选择和可配置的结果数量限制，并覆盖所请求的工作流。
