// When the sync engine moves a tracked file on disk (post-create
// deconflict, reconciler placement, lost-rename replay, slot
// displacement), shift the path's offline-protection forward
// so the random-op picker doesn't accidentally rename the
// moved file while offline. Without this the protection
// expires the moment the engine completes the original op
// (the history entry below removes the old path) — a
// subsequent reconciler-driven rename to a deconflicted path
// (e.g. `initial-1.md → initial-1 (2).md` after a same-path
// collision) lands at a path the touch-list never knew about,
// and an offline rename against that path strands the file.
