[FR] Show last line on stdout/stderr during command execution

Currently we need to press ctrl+r on the bash to show all output. It would be nice to see the last line of the stdout/stderr.

For example, this is today:

! uv run pytest
  ⎿  ============================= test session starts ==============================
     platform darwin -- Python 3.11.11, pytest-8.4.1, pluggy-1.6.0
     rootdir: /Users/username/Projects/projectname
     … +7 lines (ctrl+r to expand)

New version could look like this

! uv run pytest
  ⎿  ============================= test session starts ==============================
     platform darwin -- Python 3.11.11, pytest-8.4.1, pluggy-1.6.0
     rootdir: /Users/username/Projects/projectname
. . .
============================== 4 passed in 0.21s ===============================
     … +6 lines (ctrl+r to expand)
