feat: Add Global Macro Scanner feature

- Added market-wide analysis capabilities (movers, indices, sectors, industries, topic news)
- Implemented yfinance and Alpha Vantage data fetching modules
- Added LangChain tools for scanner functions
- Created scanner state definitions and graph components
- Integrated scan command into CLI
- Added configuration for scanner_data vendor routing
- Included test files for scanner components

This implements a new feature for global macro scanning to identify market-wide trends and opportunities.

+# Data Layer Fix and Test Plan for Global Macro Analyzer
+
+## Current State Assessment
+
+- ✅ pyproject.toml configured correctly
+- ✅ Removed stray scanner_tools.py files outside tradingagents/
+- ✅ yfinance_scanner.py implements all required functions
+- ✅ alpha_vantage_scanner.py implements fallback get_market_movers_alpha_vantage correctly
+- ✅ scanner_tools.py wrappers properly use route_to_vendor for all scanner methods
+- ✅ default_config.py updated with scanner_data vendor configuration
+- ✅ All scanner tools import successfully without runtime errors
+
+## Outstanding Issues
+
+- CLI scan command not yet implemented in cli/main.py
+- Scanner graph components (MacroScannerGraph) not yet created
+- No end-to-end testing of the data layer functionality
+
+## Fix Plan
+
+### 1. Implement Scanner Graph Components
+
+Create the following files in tradingagents/graph/:
+
+- scanner_setup.py: Graph setup logic for scanner components
+- scanner_conditional_logic.py: Conditional logic for scanner graph flow
+- scanner_graph.py: Main MacroScannerGraph class
+
+### 2. Add Scan Command to CLI
+
+Modify cli/main.py to include:
+
+- @app.command() def scan(): entry point
+- Date prompt (default: today)
+- LLM provider config prompt (reuse existing helpers)
+- MacroScannerGraph instantiation and scan() method call
+- Rich panel display for results
+- Report saving to results/macro_scan/{date}/ directory
+
+### 3. Create MacroScannerGraph
+
+Implement the scanner graph that:
+
+- Runs parallel Phase 1 scanners (geopolitical, market movers, sectors)
+- Coordinates Phase 2 industry deep dive
+- Produces Phase 3 macro synthesis output
+- Uses ScannerState for state management
+
+### 4. End-to-End Testing
+
+Execute the scan command and verify:
+
+- Rich panels display correctly for each report section
+- Top-10 stock watchlist is generated and displayed
+- Reports are saved to results/macro_scan/{date}/ directory
+- No import or runtime errors occur
+
+## Implementation Steps
+
+1. [ ] Create scanner graph components (scanner_setup.py, scanner_conditional_logic.py, scanner_graph.py)
+2. [ ] Add scan command to cli/main.py with proper argument handling
+3. [ ] Implement MacroScannerGraph with proper node/edge connections
+4. [ ] Test scan command functionality
+5. [ ] Verify output formatting and file generation
+6. [ ] Document test results and any issues found
+
+## Verification Criteria
+
+- ✅ All scanner tools can be imported and used
+- ✅ CLI scan command executes without errors
+- ✅ Rich panels display market movers, indices, sector performance, and news
+- ✅ Top-10 stock watchlist is generated and displayed
+- ✅ Reports saved to results/macro_scan/{date}/ directory
+- ✅ No runtime exceptions or import errors
+
+## Contingency
+
+- If errors occur during scan execution, check:
+  - Vendor routing configuration in default_config.py
+  - Function implementations in yfinance_scanner.py and alpha_vantage_scanner.py
+  - Graph node/edge connections in scanner graph components
+  - Rich panel formatting and output generation logic

+# Data Layer Fix and Test Plan
+
+## Goal
+
+Verify and test the data layer for the Global Macro Analyzer implementation.
+
+## Prerequisites
+
+- Python environment with dependencies installed
+- yfinance and alpha_vantage configured
+
+## Steps
+
+1. Import and test scanner tools individually
+2. Run CLI scan command
+3. Validate output
+4. Document results
+
+## Testing Scanner Tools
+
+- Test get_market_movers
+- Test get_market_indices
+- Test get_sector_performance
+- Test get_industry_performance
+- Test get_topic_news
+
+## Running CLI Scan
+
+- Command: python -m tradingagents scan --date 2026-03-14
+- Expected output: Rich panels with market movers, indices, sector performance, news, and top-10 watchlist
+
+## Expected Results
+
+- No import errors
+- Successful execution without exceptions
+- Output files generated under results/
+- Top-10 stock watchlist displayed
+
+## Contingency
+
+- If errors occur, check import paths and configuration
+- Verify default_config.py scanner_data setting is correct
+- Ensure vendor routing works correctly
+
+## Next Steps
+
+- Address any failures
+- Refine output formatting
+- Add additional test cases
