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).

A issue não especifica arquivos, testes nem um ponto de entrada. Comece localizando o tratamento existente dos comandos de seleção de modelos no Copilot CLI e como o uso dos modelos é registrado. O trabalho estará concluído quando forem implementados a listagem de modelos recentes, os metadados dos modelos, a seleção rápida e um limite configurável de resultados, com cobertura para os workflows solicitados.
