TASK-118.12	Add persistent map annotations to rmaps via Automerge	Done		2026-03-16 00:06	2026-03-16 00:50	multiplayer tier-5	Multiplayer Everything		TASK-118	low

Description

rmaps already has ephemeral WebSocket rooms for live location sharing. Add an Automerge doc layer for persistent map annotations (pins, notes, routes, areas) that survive room disconnection.

New files:

• modules/rmaps/schemas.ts — MapsDoc with annotations, savedRoutes, meetingPoints
• modules/rmaps/local-first-client.ts — CRUD: addAnnotation, saveRoute, setMeetingPoint

Schema:

MapsDoc {
  meta: { module: 'maps', collection: 'annotations', version: 1 }
  annotations: Record<string, { id, type: 'pin'|'note'|'area', lat, lng, label, authorDid, createdAt }>
  savedRoutes: Record<string, { id, name, waypoints[], authorDid }>
  savedMeetingPoints: Record<string, { id, name, lat, lng, setBy }>
}

Ephemeral room sync (live location) remains unchanged.

Acceptance Criteria

• #1 Persistent annotations survive room disconnection
• #2 Saved routes and meeting points sync via Automerge
• #3 Ephemeral live location sharing still works unchanged
• #4 Demo mode works locally
