fix(carousel): hasSubtitle + relayMessage direto + proto atualizado

Implementação completa baseada na análise ponto-a-ponto de 5 diferenças:

1. hasSubtitle adicionado ao proto schema (field 10, bool em Header)
   - Adicionado ao WAProto.proto, index.js (encode/decode/fromObject/toObject)
   - Adicionado ao index.d.ts (IHeader, Header class)
   - Usado no root header e em cada card do carousel

2. relayMessage direto para carousel em sendMessage
   - Detecta nativeCarousel no content e bypassa generateWAMessage inteiro
   - Chama generateWAMessageContent (que usa fromObject) diretamente
   - Depois relayMessage sem passar por generateWAMessageFromContent
   - Elimina: segundo WAProto.Message.create(), contextInfo.expiration, etc.

3. Pipeline final do carousel agora:
   sendMessage → generateWAMessageContent(fromObject) → relayMessage
   Sem: generateWAMessageFromContent, WAProto.Message.create, ephemeral

Commits anteriores já incluem:
- viewOnceMessage wrapper
- fromObject no generateWAMessageContent
- Skip tctoken no stanza
