fix: pass entire storage config to createStorage (gcsNativeStorage now detected)

Critical fix for GCS native storage configuration detection.

The setupStorage() method was only passing storage.type and storage.options,
but users provide gcsNativeStorage at the storage level, not inside options.

Before (broken):
  createStorage({
    type: config.storage.type,
    ...config.storage.options  // undefined!
  })

After (working):
  createStorage(config.storage)  // passes entire config including gcsNativeStorage

This fixes the "GCS native storage configuration is missing" error that caused
fallback to memory storage even when gcsNativeStorage was correctly configured.
