[FEATURE] File Refresh

## Feature Description

Is there a file refresh system [like in the other claude code neovim plugin?](https://github.com/greggh/claude-code.nvim/blob/main/lua/claude-code/file_refresh.lua) I searched through the issues but I couldn't find any complaints about it. It's not a big deal to type `:ea` after going back to an editing buffer after claude makes some edits, but it would be nice if this happened automatically (and I would prefer if it was dependent on claude code making a change and not a global neovim file refresh setting that was always running).

## Use Case

This is just a small convenience which keeps the buffers that claude code is changing live updating.

## Proposed Solution

If this is already possible somewhere, please let me know. Otherwise I can try to port the solution from the other project and make a PR.

## Alternatives Considered

typing `:ea` reloads all buffers from the files on disk

## Additional Context

N/A

Commencez par lire lua/claude-code/file_refresh.lua dans l’implémentation claude-code.nvim référencée et examinez le flux de modification de Claude Code de ce plugin. C’est terminé lorsque les buffers modifiés par Claude Code se mettent automatiquement à jour lorsqu’on y revient, sans activer un paramètre global d’actualisation de Neovim ; vérifiez le comportement par rapport à l’alternative existante :ea.
