Get default models

Returns the model new desktop chats start with on the OpenCode v2 engine: the organization default (null for none) and each team's override (null when the team uses the organization default), teams by name. A member on several teams whose overrides differ starts on the organization default; conflictingMemberCount counts them per team. Members can still change the model in each chat. Requires the View OpenWork Models settings permission and the Organization default model feature.
