New INFRA category "Herdr sessions" (purple sparkles icon between
Fleet and Local hardware). Shows a card per online fleet node with:
- Node name + hostname + IP
- Per-workspace agent state pills (working / blocked / done /
idle / unknown), colored dots + pane count
- "Open" button → renders that node's full Herdr TUI inline via
xterm.js (same nodeHerdrConnector + WebRTC-with-fallback the
MissionCanvas Live Pane uses)
Backend:
- node daemon: herdr_workspaces + herdr_snapshot ops
(`herdr workspace list`, `herdr api snapshot`)
- fleet_herdr::snapshot helper on top of hub.call_timeout
- GET /api/nodes/{id}/herdr/session route
Fetch flow: /api/nodes filtered to status='online' → for each,
/api/nodes/{id}/herdr/session in parallel. Snapshot errors surface
per-card without failing the whole grid.
The "Open" xterm is separate from the MissionCanvas Live Pane —
this one is scoped to the whole node's Herdr TUI (any workspace),
not a specific mission's pane. Operator toggles between nodes via
the buttons.
Verified: cargo check --workspace + tsc --noEmit both green.
