feat(coding-agent): make scoped models and tree filter shortcuts configurable (#3343)

- Add app.models.{save,enableAll,clearAll,toggleProvider,reorderUp,reorderDown}
- Add app.tree.filter.{default,noTools,userOnly,labeledOnly,all,cycleForward,cycleBackward}
- Migrate scoped-models-selector cancel to tui.select.cancel
- Prefer reserved actions on key collision in extension shortcut conflict check
