The hives nav tab and route go, with no redirect; the roster is a card above
the agents panel that starts folded and is read on the first open. The
settings toggle is renamed from hide debug output to hide developer details,
as it now also drops the components tab (the page still answers at
/components); the stored preference keeps its key.
The row moves from the per-agent page into @hive/shared so both pages mount
the same one. The terminal's debug rows now follow the preference as it
changes, so rows already on screen hide or show at once instead of only the
rows that arrive after the toggle.
