Versioning - App Registry

Versioning

Each app record has a version field (starts at 0). The version increments by 1 on each successful update, enable, or disable call that changes the record. Use versioning to detect concurrent modifications — if you read an app at version 3 and update it, the response returns version 4.

The version does NOT increment if an enable/disable call matches the current status (idempotent no-op).
