- PR #103999: fix(file-sync): hash the uploaded snapshot instead of mutable host files

A race condition in file sync could cause a remote upload to overwrite a newer host save with stale content. The fix hashes the uploaded snapshot rather than the mutable host files to preserve host saves during upload.
