What’s new

On-device (offline) AI overhaul.

- The high-performance "Gemma 4" model now actually runs (it was downloaded but never used)
- The light model is now "Qwen3"; initial download cut from ~570MB to ~350MB
- Fixed failing short on-device AI answers (e.g. food-name normalization)
- Preparing the high-performance model uses less storage and survives closing the app midway
- iOS: no longer auto-downloads an unused AI model (~550MB)

Unused components were removed for a lighter, more stable app.
