_build_repos emptied each lane's sessions array for the overview (hydrate=False)
payload BEFORE _sort_lanes ran. _lane_sort_key derives a lane's activity from
max(_session_time(s) for s in group["sessions"]), so with the rows already gone
every non-trunk lane scored activity=0.0 and the sort key
(is_trunk, is_kanban, -activity, label) collapsed to alphabetical-by-label. The
documented intent — branches and linked worktrees sort by most-recent activity,
then label — was silently defeated on the projects.tree RPC that feeds the
desktop sidebar overview, while the drill-in path (hydrate=True) kept the rows
and sorted correctly. Any repo with two or more non-trunk lanes showed a
different order in the overview than when opened.
Move the session-clearing to after _sort_lanes/_disambiguate_labels so the sort
reads real recency. Lane counts are still captured before clearing, so
sessionCount and the slim overview payload are unchanged — only the order is
fixed, and the overview now matches the drill-in.
