🚀 Analyze Queries with EXPLAIN and PRAGMA optimize​

Use EXPLAIN QUERY PLAN to inspect how SQLite executes queries and which indexes are used. Combine it with PRAGMA optimize to rebuild internal structures for better performance. Regular analysis helps you spot missing indexes and inefficient scans.
