Joseph O'Brien 80e8fb0eee feat: add centralized logging module with dual output support 
Add tradingagents/logging.py with JSONFormatter for structured file logs
and RichHandler for colored console output. Migrate 59 print statements
across 13 files to proper logger calls. Configure via environment
variables (TRADINGAGENTS_LOG_LEVEL, etc.) with default_config fallback.

- Rotating file handler: 10MB max, 5 backups to logs/tradingagents.log
- Rich console handler with tracebacks for development
- Logger hierarchy follows module paths (tradingagents.dataflows.*, etc.)
- 20 feature-specific tests covering core, config, migration, integration
