Add journal-tracked migration 0258 for the recommendation_id index

Generated with drizzle-kit generate, then hand-edited to IF NOT EXISTS:
the index already exists on the live DB (created CONCURRENTLY on
2026-07-02), so the migration must no-op there while still building the
index in fresh environments. Snapshot + journal are updated so the next
generated migration doesn't re-emit this index.

Applying it (drizzle-kit migrate) remains a human action.
