[BUG] VS Code Extension; Code Edits Don't Sync

What's Wrong?

I use VS code to write and compile my LaTeX documents. The new claude-code extension for VS code works great for this, because Claude really helps with editing LaTeX documents.

However, sometimes after Claude makes edits these don't get applied to the main.tex file. If you try to compile or save the main.tex, the error appears,

"Failed to save 'main.tex': The content of the file is newer. Please compare your version with the file contents or overwrite the content of the file with your changes."

If you try to overwrite, the "overwrite" doesn't actually overwrite the the changes Claude made.

What Should Happen?

Claude should be able to see edits made to main.tex even if the file has not been recompiled since then.

Error Messages/Logs

Failed to save 'main.tex': The content of the file is newer. Please compare your version with the file contents or overwrite the content of the file with your changes.

Steps to Reproduce

Open a LaTeX file with the VS code LaTeX editor. Make some changes to the file, _but do not compile or build the project!_ Claude won't see these changes on Claude's end. Then, when Claude tries to make changes it will be de-synced. If you press "overwrite" this doesn't actually apply Claude's edits (as desired.)

The way to avoid this is to just always remember to compile/build before having Claude make new edits, but this it is inconvenient to recompile after every tiny edit.
