Module error 

Unified error types for the Akar graph database.

Every crate in the workspace returns Result<T, AkarError> (or a subsystem-specific error that converts into AkarError via From).

The hierarchy is:

AkarError
├── Storage(StorageError)
├── Transaction(TransactionError)
├── Catalog(CatalogError)
├── Binder(BinderError)
├── Planner(PlannerError)
├── Processor(ProcessorError)
├── Parser(String)
├── Io(std::io::Error)
└── Internal(String)
