- Remove validation logic from calculate_tax_yearly_average()
- Add _auto_download_missing_monthly_data() for silent auto-download
- Fix duplicate validation code in CLI that caused unintended execution
- Separate validation from calculation: --stats only calculates, --validate only validates
- Maintain auto-download functionality for missing data in calculations
- Ensure stats command shows only calculation results without validation output
Root Cause: Validation code was embedded in tax calculation function and duplicated in CLI
Solution: Extract validation from calculation, keep auto-download separate
Result: --stats shows clean output, --validate provides full analysis

Record Count Analysis:
- Breaks down data by multiple time periods simultaneously
- Supports week-by-week, monthly, quarterly, half-yearly, and yearly counts
