Description

It would be useful to support methods like push, insert, and remove on models directly in .slint code, as well as for slint::Model

(Maybe using += to push.)

Original Description

Slint Vector type or modifyable Model within Slint**

Model has no way of appending or popping from within Slint. It would be good to have a Vector type that can do this.

Contributor guide

Research direction
Implement `push`, `insert`, and `remove` methods on the `slint::Model` trait and generate appropriate code for .slint models. Look at existing model implementations (e.g., `VecModel`) to understand the pattern. Consider using `+=` operator for push.
