• Save states registered in Realm on import — importSaves now registers imported save states via per-save manifest metadata, so they appear in the UI immediately without a full library re-scan.
• Export bundles include .svs.json sidecars — exportSaves copies the .svs.json metadata file alongside each .svs save-state, enabling round-trip Realm registration.
• importSaves returns SaveImportResult — callers now receive sramRestored, statesRestored, and non-fatal warnings instead of Void.
