arookieofcтаa-rookie-of-C-language 14c7821cf4 fix(vcs): stop status write-back from restoring a pre-switch index (#476)
A status run refreshes stat info in the index and writes the result back, a read-modify-write with no check that the file changed in between. A branch switch rewriting thousands of files gives a watcher-triggered status run time to land its stale snapshot over the new index, leaving the old branch staged: phantom MM/AD entries, empty diffs, and commits of the wrong tree.

The index identity is now captured before status reads the index, and the write-back is skipped if it no longer matches. This also covers git add, commit and stash run from a terminal. A false positive only drops one stat refresh.

Closes #471
