Migration Workflow in Drizzle ORM

# 1. Edit your schema file (e.g., src/db/schema.ts)
#    Add/modify tables, columns, indexes

# 2. Generate a migration
npx drizzle-kit generate
# Creates: drizzle/0001_add_user_table.sql

# 3. Review the generated SQL
cat drizzle/0001_add_user_table.sql

# 4. Apply the migration
npx drizzle-kit migrate

# 5. Check current schema status
npx drizzle-kit check

# 6. Drop a migration (if needed before applying)
npx drizzle-kit drop
