bug(tools): `editor_replace` tool clears whole file and writes it again

[Gh61]

Hello,
thank you for this extension. It is very useful for integrating AI with Visual Studio.
There are a few things missing that would make it work better for our use case.
If you do not mind, I would like to suggest a few improvements. I may even implement some of them myself in the future if I find the time.

When the AI is calling the editor_replace tool, as a result the file is completely cleared and written all over again.
This is creating 2 steps in editor history (when using Ctrl+Z), one being completely empty file.

Please improve the logic behind the editor_replace action, so it only replaces parts of the text, that are needed.
Thank you
