[feature] Run ANALYZE after migrations on SQLite

[daenney]

Description

This ensures that at the end of migrations, we run ANALYZE if we're using SQLite. This should be relatively quick and guarantees that the table and index statistics have been updated. This helps to ensure the query planner makes better choices when it comes to picking which indexes are used when running queries.
