Fleet: node hostname/IP on register + node terminal in the infra computer

Hostname/IP:
- Daemon reports the machine's hostname (sysinfo) + primary outbound IPv4 on each
  heartbeat. migrations/0021 adds nodes.hostname/local_ip; cm-db heartbeat stores
  them; node JSON exposes them. Cards now title on the real hostname (falling back
  to name) + show the IP, instead of the "New node" placeholder. `name` stays
  user-overridable (rename).

Terminal moved into the pull-out computer (no more per-card modal):
- New infra computer app NodeTerminalApp (computer/apps/infra) — xterm bridged to
  a node's host shell over the node control channel, filling the app window
  (mirrors the agent Terminal's layout + ResizeObserver). Added "terminal" to the
  INFRA_CATALOG grid; a ?node= panel param targets a specific node (picker when
  unset). Clicking Terminal on a node card now opens the infra computer to that
  node's shell instead of a separate full-screen window. Deleted NodeTerminal.tsx.

Rebuilt + re-hosted both daemon binaries (hostname change).
