Move VD1 (combo di bien) to first example so Classifier

for combo/set do queries.

- Added hard_patterns.py: detect patterns (cheaper_than, more_expensive_than, similar_to) and extract reference product
- product_search_engine.py: integrate pattern detection, auto-set price_max/min based on reference price
- lead_search_tool.py: added user_insight parameter
- graph.py: pass user_insight to tool, removed product_ids filter (always return full tool result)
- prompts.py: added family/group intent examples, emphasize product_ids must include all items
- stylist_engine.py: added occasion and rule_id to matches, save to DB properly
- Added scripts: regenerate_matches.py and test_insert_one.py

Impact:
- Query 'rẻ hơn' auto sets price_max = ref_price * 0.95
- Query 'đắt hơn' auto sets price_min = ref_price * 1.05
- UI receives complete product list from tool (not truncated by AI)

- Removed orphan folder 08-lead-search/ (replaced by 08a/08b/08c/08d)
- Removed 8 orphan HTML/MD files from lead folders
- Fixed duplicate section titles (JS h2 + MD heading)
- Progress counter now auto-counts from registry.json
- Bumped cookbook.js to v9

- Journey Shopping (5 Modes): SVG funnel + 6 sections (Overview, Modes, Stage Transition, Upsell, Personalization, Troubleshooting)
- Dual-Agent Flow: SVG architecture + 6 sections (Overview, Classifier, Stylist, State, Tracing, Troubleshooting)
- Split Query & Cascading: SVG 7-tier + 6 sections (Overview, Literal, Inferred, Cascading, Enrichment, Troubleshooting)
- Modification Guide: SVG file map + 6 sections (FileMap, Tags, Tone, Upsell, NewTool, Checklist)
- Fixed mermaid.run() API call in cookbook.js (nodes param instead of querySelectorAll string)
- Bumped cookbook.js version to v8

fix(agent): make Stylist proactive — stop asking questions, auto-build combos from suggest_items + ai_matches

feat(agent): add COMBO rules + examples to Stylist prompt — use suggest_items and ai_matches to build full outfits

feat(agent): add 6 few-shot examples to Classifier prompt for combo, correction, recall, and early exit scenarios

fix(agent): prevent classifier from inheriting narrow product_line (like underwear) when user asks for a combo/set

fix(agent): update RECALL rules to correctly route queries with gender/product corrections to search tool
