…to-end Replace the opaque event-data string surfaced from HCS live migration callbacks with a typed notification payload so callers can act on migration progress without parsing raw JSON. - Add OperationSystemMigrationNotificationInfo to the HCS schema along with MigrationOrigin, MigrationEvent, and MigrationResult enumerations covering the full set of states reported by HCS (setup, blackout, transfer, recovery, completion, failure, etc.). - Update the HCS migration callback to unmarshal the JSON event payload into the new struct, drop malformed events with a warning, and deliver typed values over MigrationNotifications() instead of raw strings. - Add unit tests for the callback handler covering nil arguments, valid payloads, empty data, malformed JSON, and a full notification channel.

Summary
Replace the opaque event-data string surfaced from HCS live migration callbacks with a typed notification payload, and propagate that shape through the migration gRPC API so callers can act on migration progress without parsing raw JSON.
