jif-oai f7e8ff8e50 Make turn diff tracking operation backed (#21180) ...

## Summary
- replace filesystem-based turn diff tracking with an operation-backed
accumulator
- preserve enough verified apply_patch state to render move-overwrite
cases correctly
- keep the turn/diff/updated contract intact while removing remote-only
turn-diff test skips

This takes the assumption that no 3P services rely on the output format
of `apply_patch`

## Why
For the CCA file system isolation push
