### Fixed

- Fix `OrchestrationState` container and sync cursor handler to support `instance_spaces` list — `save_orchestration_state` now serializes `instance_spaces` to the `instance_space` string field via `json.dumps()` with backward-compatible JSON parsing on load; sync cursor handler accepts both `instance_space` (singular) and `instance_spaces` (list), derives a stable cursor-state key, and uses an `In` filter to support multiple spaces
