The ST4TS page (/stats.html), GET /api/stats-hive, hive-c0re's hive_stats
rollup and the modelPrices option that only fed its cost estimate are
gone. Each agent's own /stats page and the turn-stats database it reads
are unchanged. Setting modelPrices now fails evaluation with a message
saying so.
The links menu moves into @hive/shared and takes its links as a prop. The swarm
UI feeds it /api/links as before; the dashboard feeds it stats, API docs and the
swarm, and mounts it next to the profile menu in place of its own hamburger on
the left. A link opens in a new tab unless its entry says it is a page of the
same site.
