Feat Workspace Undo: Take a snapshot of the workspace before each user input

[kripper]

What problem or use case are you trying to solve?

Somestimes OH modifications to the workspace are not as desired.
I noticed OH can undo file changes, but apparently only on single files and only 1 step back (?).
When we say "revert the changes", it's also not clear until which point we want OH to revert.
Having a feature to revert until a previous user input message would be nice.

Describe the UX of the solution you'd like

It would be nice to be able to edit any previous user message (just like with ChatGPT, Gemini, etc) and have OH automatically rollback the workspace to that point.

Do you have thoughts on the technical implementation?

docker commit?
