TASK-118.2	Add multiplayer sync to rchoices (voting/ranking sessions)	To Do		2026-03-16 00:05	multiplayer tier-2	Multiplayer Everything		TASK-118	medium

Description

rchoices is currently a stateless voting UI. Add Automerge-backed real-time sync for live collaborative voting sessions.

New files:

• modules/rchoices/schemas.ts — ChoicesDoc with votingSessions, votes, rankings
• modules/rchoices/local-first-client.ts — CRUD: createSession, castVote, updateRanking

Schema design:

ChoicesDoc {
  meta: { module: 'choices', collection: 'sessions', version: 1 }
  sessions: Record<string, { id, title, type: 'vote'|'rank'|'score', options: [], createdBy, createdAt }>
  votes: Record<string, { sessionId, participantDid, choices: Record<optionId, number>, updatedAt }>
}

Component updates (folk-choices-*.ts):

• Init local-first client, subscribe to doc changes
• Real-time vote tally updates as participants vote
• Show participant count and live results

Acceptance Criteria

• #1 Voting sessions sync in real-time between participants
• #2 Vote tallies update live as votes come in
• #3 Session creator can configure vote type (single/multi/ranked)
• #4 Demo mode works with local-only state
