fix: Initialize logger before use in github_scraper.py

Fixes Issue #190 - "name 'logger' is not defined" error

**Problem:**
- Logger was used at line 40 (in code_analyzer import exception)
- Logger was defined at line 47
- Caused runtime error when code_analyzer import failed

**Solution:**
- Moved logging.basicConfig() and logger initialization to lines 34-39
- Now logger is defined BEFORE the code_analyzer import block
- Warning message now works correctly when code_analyzer is missing

**Testing:**
- ✅ All 22 GitHub scraper tests pass
- ✅ Logger warning appears correctly when code_analyzer missing
- ✅ No similar issues found in other CLI files

Closes #190
