Sansan 07e9fd6c56 test: Add migration test with manual data insertion
- TestMigrationsStepByStep: tests incremental migration workflow
  - Step 1: Apply first 4 migrations (creates game, song tables)
  - Step 2: Manually insert 5 games with 8 songs
  - Step 3: Apply migration 5 (rename game→soundtrack)
  - Step 4: Verify data preserved in soundtrack table
- Helper functions: cleanupDB, createTestDB, applyMigrations
- Tests data integrity through full migration cycle

Note: Test requires PostgreSQL connection with appropriate permissions.
Configure test DB in migration_test.go or use existing test infrastructure.
