 * Base class for all library errors. Extends the native {@link Error} so that
 * the near-universal `err instanceof Error` idiom (and the diagnostics /
 * telemetry utilities built on it) correctly classifies every domain error
 * derived from this class.
 *
 * Subclasses set their human-readable `name` from the static `type` property
 * (falling back to the runtime constructor name). An optional `cause` may be
 * supplied via the second constructor argument and is propagated to the native
 * `Error` cause chain.
