perf: remove Gemini from bringSuggest and product selection - pure offline logic
- bringSuggestItems: now uses smart_shopping cache (already computed offline)
instead of calling Gemini with full inventory prompt
- aiSelectBestProduct: replaced Gemini call with token-scoring algorithm;
scores by token overlap, first-anchor bonus, spec-variant matching,
category mismatch penalty — 0ms vs ~1s per product search
- Only truly necessary AI calls remain: photo expiry, photo identify,
chat assistant, recipe generation
