[Gastown] PR 7: Basic Dashboard UI

[jrf0110]

Parent: #204 | Phase 1: Single Rig, Single Polecat

Goal

Minimal UI to create a rig, sling work, and watch an agent work. Thin first pass following existing dashboard patterns.

Pages

Route	Component	Purpose
/gastown	Town list	List user's towns, create new
/gastown/[townId]	Town overview	List rigs, active convoys
/gastown/[townId]/rigs/[rigId]	Rig detail	Bead board, agent list, agent stream

Key Components

• Bead board: Simple list/kanban of beads by status (open → in_progress → closed). Read from DO via tRPC → Gastown worker API.
• Agent card: Shows agent identity, status, current hook. Links to conversation stream.
• Agent stream: WebSocket connection to the container's stream endpoint (via getAgentStreamUrl tRPC query). The container proxies Kilo CLI output events.
• Sling dialog: Form to create a bead and assign it. Inputs: title, body, model selector.
• Mayor chat: Direct message input that sends to the Mayor agent. Uses sendMessage tRPC mutation.

Revised: Agent stream now connects to the Town Container's stream endpoint instead of cloud-agent-next WebSocket. Mayor chat input added.

Dependencies

• PR 6 (tRPC Routes) — [Gastown] PR 6: tRPC Routes — Town & Rig Management #268

Acceptance Criteria

• Town list page with create town form
• Town overview page showing rigs
• Rig detail page with bead board, agent cards, and agent stream
• Sling dialog that creates a bead and starts a polecat (via alarm dispatch)
• Agent stream component connecting to container's WebSocket
• Mayor chat input component
• Responsive layout following existing dashboard patterns
