fix(runtime): flag cross-cluster orphan-equipment bindings on rebuild

ParseComposition(blob, nodeId, onInconsistency?) detects a kept equipment whose
UNS line belongs to another cluster (a same-cluster-invariant violation that
would orphan the equipment folder) and reports it via an optional callback,
wired to OpcUaPublishActor's logger. Detection-only; the upstream draft
validator remains the authority. Adds two unit tests.
