Description

rtube is a community video hosting UI. Add Automerge sync for shared playlists and watch party queue state.

New files:

• modules/rtube/schemas.ts — TubeDoc with playlists, watchParty, queue
• modules/rtube/local-first-client.ts — CRUD: createPlaylist, addToPlaylist, updateQueue

Schema:

TubeDoc {
  meta: { module: 'tube', collection: 'playlists', version: 1 }
  playlists: Record<string, { id, name, videoIds[], createdBy, updatedAt }>
  watchParty: { active: boolean, currentVideoId, position, hostDid, participants[] }
  queue: string[]
}

Acceptance Criteria

• #1 Playlists sync across space members
• #2 Watch party state (current video, position) syncs in real-time
• #3 Demo mode works with local-only state
