Serialize batch state checkers per permission in dynamic distribution

- Add state-aware overload to ISimpleStateCheckerSerializer/Contributor
- Features and Permissions contributors recognise their batch checker and emit a per-state record
- PermissionDefinitionSerializer threads the owning permission through
- Pin equality semantics to match the batch runtime (default comparer)
