## Description
<!-- SECTION:DESCRIPTION:BEGIN -->
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
<!-- SECTION:DESCRIPTION:END -->
## Acceptance Criteria
<!-- AC:BEGIN -->
- [ ] #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)
