feat: smart base image check with docker pull

- Use 'docker pull' to check if base exists
- If exists: skip build (saves ~10 minutes) ✅
- If not exists: build automatically
- Single stage that handles both check and build
- No authentication issues (uses docker login)

Behavior:
✓ Base exists → Skip (~30 seconds check + 3 min app)
✓ Base missing → Build base (~10 min) + app (~3 min)

This is the REAL solution we wanted!
