 * Walk a chain of `Got<Submodel>Message` wrappers in a recorded Message and
 * return the wrapper tags plus the innermost leaf tag.
 *
 * The Submodel pattern propagates child Messages up to a parent by wrapping
 * them in `GotChildMessage({ message: childMessage })`. Nested submodels stack
 * those wrappers. Walking the chain reveals the parent → child → grandchild
 * dispatch path that produced the entry.
 *
 * Returns an empty path and `Option.none` for top-level Messages whose tag
 * doesn't match the `Got*Message` pattern. Otherwise the path lists wrapper
 * tags from outer to inner, and `maybeLeafTag` is `Some` when the innermost
 * wrapped value is itself a tagged Message (the underlying child Message that
 * originated the chain).
