fix(editing-context): trust parentId chain without re-checking ancestor match()

Parent match() functions are designed for flat priority resolution and
may not return true when a more specific child is active (e.g.
assembly.idle checks getActivePartObject() which may not return the
assembly during edit mode). The parentId declaration is the author's
assertion of structural containment — the leaf already matched, so
we walk the full chain unconditionally.
