Subject: [PATCH] feat: show last-run duration on the groups list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

groups_index attaches last_duration_s from the latest group run; groups.html
renders it as a new right-aligned duration column (— when never run).
