…ions (HKUDS#351) Extract `ComposerInput` component to isolate frequent keystroke renders. Refactor `ChatComposer` to use `hasContent` flag instead of full `input` state. Apply `React.memo` to heavy config panels (Quiz, Math, Research, Visualize). Stabilize parent callbacks in `ChatPage` using `useCallback`. Fix residual syntax errors and missing `canSend` definition in composer. Address HKUDS#351 by implementing deep state colocation.
Extract lightweight `SimpleComposerInput` to isolate keystroke renders. Colocate input state in `agents/[botId]/chat/page.tsx` to prevent full-page lag. Export @mention utility helpers from `ComposerInput.tsx` for cross-component use. Address follow-up feedback from StarNight2021 regarding tutorbot-only performance. This completes the performance overhaul by ensuring all chat entry points use optimized state colocation patterns.
