Fix spec_runner.py path resolution after move to runners/ directory

- spec_runner.py: Update sys.path to add parent directory (auto-claude/)
  instead of current directory (runners/) so imports work correctly
- spec_runner.py: Fix .env file path resolution for the new location
- analyzer.py: Add CLI entry point to shim so it works when run as script
