Add simple progress indicator for long-running operations

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS 15.5.0 (24F74)

### Expected behaviour

Show a simple progress bar ([████████░░] 80%) or percentage (80%) for operations that take more than 2-3 seconds to complete. The indicator should update in place without creating scrolling text and clear when the operation finishes.

### Actual behaviour

> a simple progress indicator would be much better than verbose status messages. A clean `[████████░░] 80%` or just `80%` would give users the feedback they need without cluttering the interface.

This would be especially useful for:
- AWS CLI calls that take time (large resource queries)
- File operations on big directories
- CDK/Terraform operations
- MCP server tool calls

The implementation could be as simple as:
- Show progress inline where the cursor is
- Update in place (no scrolling text)
- Clear when complete
- Maybe just show for operations taking >2-3 seconds

Would you like me to help you submit this as a feature request to the Q team? A minimal progress indicator like this would be a great UX improvement without adding complexity.

El issue no menciona archivos, pruebas ni puntos de entrada. Empieza rastreando cómo la CLI renderiza operaciones de larga duración de AWS, de archivos, de CDK/Terraform y de MCP; después, define una operación acotada y el comportamiento del terminal que se deben validar; el trabajo estará terminado cuando las actualizaciones de progreso aparezcan en el mismo lugar y desaparezcan limpiamente al completarse.
