test: Add AstroValley unified config and verify AI enhancement

Added comprehensive test config for AstroValley demonstrating:
- Unified scraping (GitHub repo + codebase analysis)
- Standalone codebase skill generation working
- Combined skill generation working (264 → 966 lines)
- AI enhancement on standalone skill (89 → 733 lines, 8.2x growth)
- AI enhancement on unified skill (264 → 966 lines, 3.7x growth)

Verified AI context awareness:
✓ Standalone: Correctly identified as codebase-only (deep API focus)
✓ Unified: Correctly identified as GitHub+codebase (ecosystem focus)
✓ Smart summarization triggered appropriately (63K → 22K chars)
✓ Reference file integration working (20 files vs 8 files)

Test results:
- Both enhancement modes work perfectly
- Context-aware content adaptation confirmed
- Different use cases optimized correctly
- All systems operational
