Confusing/inconsistent recent models UX

[ariane-emory]

Description

Presently, opencode stores (and cycles between, with the model_cycle_recent/model_cycle_recent_reverse commands) 10 recent models, but the list displayed in /models only shows 5. This is a confusing and inconsistent UX: if I look at /models and only see a certain 5 models, it's surprising to see additional models in the cycle when I use the model_cycle_recent/model_cycle_recent_reverse commands.

Ideally, we should add a tui.recent_models_count setting to allow the user to configured the number of recent models that are stored/displayed. We don't want to change the logic behind which models are stored/displayed, we only want to change how many.
