What happened?

useGeminiStream.ts is over 70KB and handles everything from API orchestration to tool execution and UI animation state. This makes the logic untestable and highly prone to regression.

What did you expect to happen?

Extract the streaming and tool-handling logic into a core service and use the hook only for React state synchronization.
