Site count in tab label and footer now reflects total monitors
(excluding groups) regardless of collapse state. Down count also
computed from all sites so collapsed groups with down children
still surface in the badge. Replaced Nerd Font folder glyphs
with standard Unicode triangles for cross-font compatibility.
Add alternating row backgrounds for easier table scanning. Detail panel
now shows breadcrumb path (Sites > Group > Name) and min/avg/max latency
stats below the sparkline. Group collapse state persists across restarts
via new preferences table in both SQLite and Postgres.
Group rows now show selection background when navigated to. Layout
chrome extracted to named constants to prevent viewport drift. Groups
display aggregate history as dot sparkline (●) distinct from site
bar sparklines, with uptime computed from active children only.
Paused and maintenance children excluded from group aggregates.
