- A reload that drops a module's last require() edge leaves the permanent
hooks serving it from the synchronous snapshot map, which was only
refreshed while the path stayed flagged; an edit after the downgrade
replayed stale bytes. Ensure now re-rewrites and refreshes the snapshot
for every ever-synchronous path on each graph walk.
- Added the mirror reload regression (require edge dropped + source edited).
