# T01: Added GET /api/v1/stats endpoint returning live technique_count (21) and creator_count (7) from PostgreSQL

**Added GET /api/v1/stats endpoint returning live technique_count (21) and creator_count (7) from PostgreSQL**

## What Happened

Created backend/routers/stats.py with an async endpoint running COUNT(*) queries against TechniquePage and Creator tables. Registered the router in main.py with /api/v1 prefix. Pushed to GitHub, rebuilt the API container on ub01, and verified both counts are positive against the live database.

## Verification

Both slice-level verification commands pass: JSON assertion confirms technique_count=21 and creator_count=7 (both >0), HTTP status returns 200.

## Verification Evidence

| # | Command | Exit Code | Verdict | Duration |
|---|---------|-----------|---------|----------|
| 1 | `curl -s http://ub01:8096/api/v1/stats | python3 -c "import sys,json; d=json.load(sys.stdin); assert d['technique_count']>0 and d['creator_count']>0"` | 0 | ✅ pass | 1000ms |
| 2 | `curl -s -o /dev/null -w '%{http_code}' http://ub01:8096/api/v1/stats` | 0 | ✅ pass (200) | 1000ms |
