Hub stage 2: read-only Technitium-compatible server over several servers

node:http server that serves the console build and a /api/* the console accepts:
its own login and session (clusterInitialized, the servers as nodes, hub flag,
Dashboard and Logs only), node=<id> forwarded with that server's token, no node or
cluster merged (stats, top lists, query logs, apps), every write refused with 403,
a short response cache, and an unreachable server reported as hubWarnings. The dev
mock takes --port and --scale so two of them differ. Vitest skips .claude/ worktrees.
