BREAKING CHANGE(core): rebrand from smarts3 to smartstorage

- Package renamed from @push.rocks/smarts3 to @push.rocks/smartstorage
- Class: Smarts3 → SmartStorage, Interface: ISmarts3Config → ISmartStorageConfig
- Method: getS3Descriptor → getStorageDescriptor
- Rust binary: rusts3 → ruststorage
- Rust types: S3Error→StorageError, S3Action→StorageAction, S3Config→SmartStorageConfig, S3Server→StorageServer
- On-disk file extension: ._S3_object → ._storage_object
- Default credentials: S3RVER → STORAGE
- All internal S3 branding removed; AWS S3 protocol compatibility fully maintained
