[FEATURE] Quick Model Switching for Extension & CLI

Problem Statement

Since Haiku is the fastest model, doing configuration or repeated tasks is mostly easier with it. It's also better than Claude 4.5 for UI work. So I have to constantly switch between multiple models, and using the _VS Code native extension_ through the UI is hard and annoying because every time I have to run the command /select model and then select the model. Same issue with the CLI.

Proposed Solution

It would be better if both the extension and CLI had a keybind to quickly swap models. The extension should also have a model switcher button alongside the "plan mode" and "edit automatically" buttons. For the CLI, the keybind alone would be enough.

Alternative Solutions

Model aliases/shortcuts

Create short commands like /h for Haiku, /s for Sonnet
Much faster than typing full model names

Priority

Medium - Would be very helpful
