[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
