-- Add 'pending_review' to initiative status enum.
-- SQLite text columns don't enforce enum values at DDL level,
-- so no schema change is needed. This migration exists for documentation
-- and to keep the migration sequence in sync with schema.ts changes.
-- The Drizzle ORM schema definition now includes 'pending_review' in the
-- initiatives.status enum: ['active', 'completed', 'archived', 'pending_review']
