[FEATURE] Add line numbers to "Updated" output from the edit tool.

Problem Statement

Currently the output looks like

Update(foo)
  ⎿  Updated foo with X addition(s) and Y removal(s)
       NNN ...
       NNN ...
       ...

If I have that in VSCode terminal and want to navigate to the edit (to see bigger context, tweak the code, whatever), I have to Ctrl-click on "foo" (brings up the correct file in the editor), then manually navigate to the right line number, which is inconvenient.

Proposed Solution

Change the 2nd line to: Updated foo:NNN-NNN with X addition(s) and Y removal(s)

This would result in Ctrl-click going to the right place - ought to be an extremely trivial change to the UI that would result in a huge convenience boost to all Claude users that run it inside any IDE that can recognize the file:lineno convention in the terminal!
