Plan 09 — Fleet view (Squads + Pool + Agents)

[carlomigueldy]

Plan file: docs/superpowers/plans/2026-05-23-plan-09-fleet-view.md
Tag at close: v0.0.9-plan-09
Depends on: Plans 07 + 08

Goal

Render the fleet — the Control Room's primary view per spec §7. Subscribe to squad.changed + agent.statusChanged notifications, query squad.* / pool.list / task.list via TanStack Query, and surface squads (with leader badges), the free pool, agents (with status pills), and the active workspace's outstanding tasks.

Deliverable

• features/fleet/ feature module with TanStack Query orchestration.
• IPC notification → query invalidation bridge (useFleetSubscription).
• <SquadCard>, <AgentChip>, <PoolList>, <FleetHeader> — all oklch-themed.
• Playwright test with seeded fixtures.
• F53–F58.

Out of scope (deferred to later plans)

• Task lifecycle UI → Plan 12
• Activity + Replay → Plan 13
• Settings + Adapters → Plan 14
• Drag-and-drop pool → squad assignment → out of scope until v1.1
