Comprehensive GitHub Import Workflow Tests

Tests GitHub repository import and integration capabilities:
- Import public repositories
- Extract repository metadata (README, structure, dependencies)
- Create projects from GitHub repos
- Sync repository updates
- Clone repository content
- Code analysis from imported repos
- Dependency extraction (requirements.txt, package.json, etc.)
