Create once
A host ref and mount effect create the real CodeMirror view.
ONE PACKAGE INSTANCE · ONE OWNER · ZERO WIDGET RUNTIME
Ordinary mount and dependency effects can share one proven package handle while Kudzu keeps cleanup, remount, and browser output owner-scoped.
RETAINED INSTANCE OWNERSHIP
A host ref and mount effect create the real CodeMirror view.
Later dependency effects update the same package instance.
Editor transactions update ordinary application state.
Package update failures remain accessible application-owned state.
Conditional and document release destroy the owned view once.
No React island, ResourceIR, widget registry, or component runtime ships.
