Create regular SQLite indexes on columns used in filters and joins to improve read performance.

Enforce uniqueness and improve lookup performance in SQLite using UNIQUE indexes.

Build multi-column indexes in SQLite and apply leftmost-prefix rules to match query patterns correctly.

Remove unneeded SQLite indexes safely with DROP INDEX and verify cleanup with metadata commands.
