David decided: Decided to gate 'agents has its own computer' and assignment candidates behind pro plan

David framed the feature decision precisely:

i want you to change the default model in the dropdown from "auto" to gemini 3 flash. and also, i want you to make that "agents -- has its own computer" only a pro feature. ie. similar to the other models that are blocked for free/plus users, block that model too for free/plus users in the model dropdown. go onto the production db and codebase and study how plan limits and gating works so you implement it correctly and dont invent a new system - just use the existing system. further, for free/plus users, ensure when they click on assignment candidates in the university app home page, or in the menu bar of the interactive workspace ai chat, that it doesnt open and that no openclaw agent gets initialised and that no prefetching happens etc but rather the upgrade popup

David's instruction to study the existing gating system before writing any code reflects his preference for building on existing infrastructure rather than inventing parallel solutions.
