What
In laptop-generation sync, moving files to the trash and updating the scratch index now carry each path's raw bytes (pathBytes) instead of text. File removals are also passed to git as raw bytes rather than joined strings, and the record of trash moves is rebuilt from a diff limited to the removed paths.
Why
File names that are not valid UTF-8 text are no longer mangled, which could otherwise lead to the error "could not account for the trash moves".
