File Edition Output

When a file edition output is made, it is not super useful it outputs the diff followed by 


```
✓ Edit File pkg/session/store.go
|
...
DIFF
...
│-> output:
│File edited successfully. Replaced 596 characters
```
I think the output is not really useful here. I would skip it entirely, unless there is an error in which case I like to know. If not just don't say anything. Move along.
