Hand applied transitions to the component watcher only after the workspace
records their undo entry. Keep the handoff synchronous with the captured
prior file data. This preserves transaction order when nesting triggers
several component syncs. Fix F137.
The minimal replay failed both undo and redo before the fix; its 4 checks
now pass. Existing sync scenarios pass their behavior and undo checks;
60 golden digests need review for the accumulated Phase 4 fixes.
Common benchmark ratios against Phase 1e: main 10/100/1000
0.46/0.52/0.53; levels 0.47; chain 0.51; library 0.51; many 0.49;
switch 0.61. This handoff changes no common benchmark code.
