[BUG] /rewind shows "Restore code" option intermittently or fails to restore files

Preflight Checklist

• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

When using /rewind to restore code to a previous checkpoint, the feature behaves inconsistently:

"Restore code" option is sometimes missing from the rewind menu
Partial restoration: Only some modified files are restored, not all of them
Debug logs show 0 files tracked at snapshot creation, even though file modifications occur afterward

What Should Happen?

The "Restore code" option should always appear when code changes exist
All file modifications made through Claude's editing tools should be restored to their previous state

Error Messages/Logs

Using claude -d2e 2> >(grep -i FileHistory > rewind.log):

2025-12-15T01:51:09.338Z [DEBUG] FileHistory: Added snapshot for 0c4e296c-c89b-43c6-a8d2-993aedc862d5, tracking 0 files
2025-12-15T01:51:27.357Z [DEBUG] FileHistory: Tracked file modification for /Users/xxx/Code/src/app/[locale]/page.tsx

Steps to Reproduce

1. Ask Claude to modify a file (e.g., "Change the title color to blue in page.tsx")
2. Wait for Claude to complete the modification using its file editing tools
3. Run /rewind to view checkpoints
4. Observed: "Restore code" option is missing, or selecting it only restores some files
