Defer edit-subclass caveat remedy past this stage

Maintainer disposition: no Phase 4 fix or wine-access defect branch for the pre-attached edit subclass; record it honestly in the Phase 4 results. Future work item: dynamic add/remove of hook exclusions inside the running helper.

+Maintainer disposition, 2026-11-01: **deferred; do not fix in

+Rationale: tearing down helper/subclass state early risks
+disturbing programs that rely on the live helper's controller and
+review services; fresh processes are fully gated, and restarting
+the prefix restores the expected state. The surprise for an
+unsuspecting user who lists an already-running editor is
+acknowledged and must be recorded honestly in the Phase 4
+results, not silently treated as passing. Future work item,
+outside this stage unless the maintainer reopens it: teach
+wine-access dynamic add/remove of hook exclusions inside the
+running helper—updating foreground gating and silencing or
+detaching pre-attached edit subclasses—rather than relying only
+on helper restart plus fresh-process semantics.
