Alice T'Poteat 7dd0636111 diff: run git when the built-in panel would, never at the session's start (#94594)
* diff: the session's start asks nothing of the repository; /diff or the first edit pins it when it comes

* diff: git runs when the built-in panel's would: one rev-parse at first need, the tree walked only for an open pane, nothing after a turn or a refused tool

* diff: a shell command that failed or was cut short still refreshes an open pane, an edit that did opens nothing, and a probe /clear overtook pins nothing
