Problem:
Every question sent via the GenAI module hits the Sugar-AI
server even if the same question was asked recently. This
wastes quota and slows response time for children.

Proposed Solution

• Add a simple local dict-based or JSON cache in the GenAI folder
• Cache responses for identical questions per session
• Add a cache size limit to avoid memory issues

Expected Outcome
Faster responses for repeated questions + reduced server load.

I'm a GSoC 2026 contributor and would love to work on this!
