```
agent: Do not render unnecessary lines in edit file tool card (#29766)

This PR prevents any unnecessary lines from being rendered in the edit
file tool card in the case of small diffs.

I think this (hopefully) addresses the last remaining task from
https://github.com/zed-industries/zed/pull/29448.

(The last empty line in the second image is an empty line present in the
file itself)

n the second commit I also preemtively disabled vertical overscrolling
for full mode editors which are sized by content. This is basically the
same fix as in https://github.com/zed-industries/zed/pull/28471.
Strictly speaking, this is not needed for the fix here, but I thought it
might be nice to have for the future to prevent any issues from occuring
due to overscroll.

Release Notes:

- agent: Improved rendering of small diffs for the edit file tool card.
