Exceptions

InvalidOperationIdException     — malformed "package.component.worker::operation" id.
InvalidDiscoveryIdException     — malformed discovery id passed to Explorer::describe().

ResolverException
├── InvalidParameterTypeException — a scalar parameter has the wrong native type.
└── MissingParameterException     — a required parameter is absent.

ObjectFactoryException
├── ClassNotFoundException            — fromArray() target class doesn't exist.
├── FromArrayMethodNotFoundException  — target class has no static fromArray().
└── NoDeserializerFoundException      — no registered deserializer, and the fallback failed too.

OperationNotFoundException  — the operation does not exist as a public method of the worker.
OperationNotAllowedException — the operation exists, but the active OperationPolicyInterface rejects it.

Every exception exposes a semantic static factory (InvalidOperationIdException::forId(), MissingParameterException::forParameter(), etc.) instead of a public constructor, and is translatable via derafu/translation.
