Critical bugfix: Scanner modules weren't being imported, causing
SCANNER_REGISTRY to remain empty and discovery to return 0 candidates.
Root Cause:
- Import line "from tradingagents.dataflows.discovery import scanners"
was accidentally removed during concurrent execution refactoring
- Without this import, scanner @register() decorators never execute
- Result: SCANNER_REGISTRY.get_all_scanners() returns empty list
Fix:
- Restored scanner import in discovery_graph.py line 6
- Scanners now properly register on module import
- Verified 8 scanners now registered and working
Impact:
- Before: 0 candidates, 0 recommendations
- After: 60-70 candidates, 15 recommendations (normal operation)

When multiple primary vendors are configured (e.g., 'reddit,alpha_vantage'),
the system now correctly stops after attempting all primary vendors instead
of continuing through all fallback vendors.
Changes:
- Track which primary vendors have been attempted in a list
- Add stopping condition when all primary vendors are attempted
- Preserve existing single-vendor behavior (stop after first success)
This prevents unnecessary API calls and ensures predictable behavior.
- Replace hardcoded column indices with column name lookup
- Add mapping for all supported indicators to their expected CSV column names
- Handle missing columns gracefully with descriptive error messages
- Strip whitespace from header parsing for reliability
