David decided: Switched calendar agent model from OpenAI to Gemini 2.5 Flash Lite

David initiated a research-first migration decision:

go study the model configurations for the module planner and the calendar agents. then go study, online, geminis docs, along with the model configurations for all gemini models we use in our codebase eg in the lecture notes agent. then, i want you to come up with a plan to switch the calendar agent and module planner from using the current openai models that they use, to using gemini 2.5 flash lite with high thinking level

When the agent proposed different models for each, David pushed for consistency:

i think lets try gemini 2.5 flash lite for both... but lets do research into their thinking budgets

He verified the API setup matched what the lecture notes agent used:

ok and are you correctly usign the gemini setup that we use when doing lecture notes generation? cause remember the calendar agent needs to be able to call tools like view file and be able to have the file inserted to it etc

The goal was parity with the existing lecture notes agent implementation, not just a model swap.
