- Reduced historical data from 4,442 daily entries to 636 weekly entries - This improves chart rendering performance and ensures all data up to current date is displayed - Updated btcpoll.js to handle weekly data updates (updates same week or adds new week) - Added aggregate-weekly.js script for future data aggregation needs - Data now properly displays from 2013-09-15 to 2025-11-09
