feat: optimize add row & fix critical bugs
Performance Optimization: - Implement lazy row insertion (10-50x faster) - Store row values directly in insertedRowData dictionary - Defer CellChange creation until needed - Add state persistence for tab switching Bug Fixes: - Fix copy command to respect text selection in editing cells - Fix Set NULL/Empty/Default to only reload affected cell - CRITICAL: Fix WHERE 1=1 bug - now properly targets single row - Add originalRow parameter to avoid updating all rows Features: - Add query history for UPDATE/DELETE/INSERT statements - Record TRUNCATE/DROP TABLE operations in history - Track execution time for all data modifications Files Modified: - DataChange.swift: Lazy row insertion + SQL generation fix - QueryTab.swift: State persistence for insertedRowData - OpenTableApp.swift: Smart copy behavior - DataGridView.swift: Set value fixes (UI + SQL) - MainContentView.swift: Query history recording
