Subject: [PATCH] fix(db): check column existence before creating performance
 indexes

_ensure_indexes() now verifies the target column exists in the table
before executing CREATE INDEX IF NOT EXISTS. This prevents failures
when migrating legacy database schemas that don't yet have all columns
(e.g. files table without created_at or mime_type).
