Subject: [PATCH] fix(interpreter): implement Unwrap on query error types
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

QueryBalanceError and QueryMetadataError wrap a store error but did not
implement Unwrap, so errors.Is / errors.As could not reach the wrapped
cause — callers only saw the message. Implement Unwrap on both so the
wrapped store error stays reachable through the chain.
