feat: add pastParticipants support in history sync

Surfaces past group participant data from WhatsApp history sync messages.
Previously pastParticipants was dropped during event buffering because
it was overwritten instead of accumulated across chunks.

- src/Types/Events.ts: add pastParticipants to BaileysEventMap['messaging-history.set'] and BufferedEventData.historySets
- src/Utils/event-buffer.ts: accumulate pastParticipants via spread array instead of overwriting; include in consolidateEvents output
- src/Utils/history.ts: pass item.pastParticipants in processHistoryMessage return

-# Mensagens View-Once (Visualização Única) — Guia de Implementação
-
-**Data:** 2026-03-23
-**Versão:** 1.0
-
----
-
-## 1. O que é View-Once
-
-Mensagem de visualização única é um tipo especial de mídia (imagem, vídeo ou áudio) que o destinatário pode abrir apenas uma vez. Após abrir, o conteúdo some permanentemente.
-
----
-
-> ## ⚠️ RESTRIÇÃO CRÍTICA — Contas Hosted (Meta Business Cloud API)
->
-> **Contas registradas como "hosted" na Meta Business Cloud API têm view-once bloqueado pelo servidor do WhatsApp.**
->
-> Essa restrição se aplica a **todos os clientes** (Android, iOS, WA Web) e **não há como contornar por código** — é uma política imposta diretamente pelo servidor WA para contas hosted.
->
-> **Como identificar se sua conta é hosted:**
-> - A conta foi criada via Meta Business Cloud API (WABA)
-> - Aparece como "Meta" ou "Business Cloud" nas configurações do WhatsApp Business Manager
->
-> **Contas não-hosted** (registradas diretamente via QR code ou pair code) **funcionam normalmente** com view-once.
-
----
-
-**Comportamento em cada dispositivo após envio via API (contas não-hosted):**
-
-| Dispositivo | O que aparece |
-|---|---|
-| Destinatário (Android/iOS) | Recebe a mídia com ícone de olhinho — pode abrir uma vez |
-| Android principal do remetente | Mostra na conversa que a mensagem foi enviada (ícone de olhinho) |
-| WA Web do remetente | "Aguardando mensagem. Abra o WhatsApp no seu celular." |
-
-> **Nota:** A mensagem "Aguardando mensagem..." no WA Web é o comportamento correto e esperado quando o envio vem de um companion (API). É uma limitação do protocolo WhatsApp — o servidor só permite que o celular principal notifique companions com o conteúdo da view-once.
-
----
-
-## 2. Como Enviar via API
-
-### 2.1 Imagem
-
-```bash
-curl -X POST https://sua-api.com/v1/messages/send_image \
-  -H "Content-Type: application/json" \
-  -H "x-api-key: SEU_API_KEY" \
-  -d '{
-    "instance": "nome-da-instancia",
-    "to": "5511999999999",
-    "caption": "Olha só isso!",
-    "imageUrl": "https://exemplo.com/foto.jpg",
-    "viewOnce": true
-  }'
-```
-
-**Resposta de sucesso:**
-```json
-{ "ok": true }
-```
-
-### 2.2 Vídeo
-
-```bash
-curl -X POST https://sua-api.com/v1/messages/send_video \
-  -H "Content-Type: application/json" \
-  -H "x-api-key: SEU_API_KEY" \
-  -d '{
-    "instance": "nome-da-instancia",
-    "to": "5511999999999",
-    "caption": "Assista uma vez",
-    "videoUrl": "https://exemplo.com/video.mp4",
-    "viewOnce": true
-  }'
-```
-
-### 2.3 Áudio
-
-```bash
-curl -X POST https://sua-api.com/v1/messages/send_audio \
-  -H "Content-Type: application/json" \
-  -H "x-api-key: SEU_API_KEY" \
-  -d '{
-    "instance": "nome-da-instancia",
-    "to": "5511999999999",
-    "audioUrl": "https://exemplo.com/audio.ogg",
-    "ptt": false,
-    "viewOnce": true
-  }'
-```
-
-### 2.4 Usando Base64 (sem URL pública)
-
-```bash
-curl -X POST https://sua-api.com/v1/messages/send_image \
-  -H "Content-Type: application/json" \
-  -H "x-api-key: SEU_API_KEY" \
-  -d '{
-    "instance": "nome-da-instancia",
-    "to": "5511999999999",
-    "imageBase64": "data:image/jpeg;base64,/9j/4AAQSkZJRgAB...",
-    "viewOnce": true
-  }'
-```
-
----
-
-## 3. Como Receber via Webhook
-
-Quando um contato envia uma mensagem de visualização única para o número conectado na API, o webhook recebe o evento com `key.isViewOnce = true`.
-
-### 3.1 Estrutura do evento recebido
-
-```json
-{
-  "event": "messages.upsert",
-  "instance": "nome-da-instancia",
-  "data": {
-    "messages": [
-      {
-        "key": {
-          "remoteJid": "5511999999999@s.whatsapp.net",
-          "fromMe": false,
-          "id": "3EB0ABCDEF123456",
-          "isViewOnce": true
-        },
-        "message": {
-          "viewOnceMessageV2": {
-            "message": {
-              "imageMessage": {
-                "url": "https://mmg.whatsapp.net/...",
-                "mimetype": "image/jpeg",
-                "mediaKey": "base64...",
-                "fileEncSha256": "base64...",
-                "directPath": "/v/...",
-                "viewOnce": true
-              }
-            }
-          }
-        },
-        "messageTimestamp": 1742700000,
-        "pushName": "João Silva"
-      }
-    ],
-    "type": "notify"
-  }
-}
-```
-
-### 3.2 Como identificar que é view-once
-
-O campo principal para identificar é `key.isViewOnce = true`. Existem dois caminhos para confirmar:
-
-```javascript
-function isViewOnce(msg) {
-  // Caminho 1: flag direta (mais simples)
-  if (msg.key?.isViewOnce) return true
-
-  // Caminho 2: verificar o wrapper da mensagem
-  const inner =
-    msg.message?.viewOnceMessageV2?.message ||
-    msg.message?.viewOnceMessage?.message ||
-    msg.message?.viewOnceMessageV2Extension?.message
-
-  return !!(
-    inner?.imageMessage?.viewOnce ||
-    inner?.videoMessage?.viewOnce ||
-    inner?.audioMessage?.viewOnce
-  )
-}
-```
-
-### 3.3 Como acessar a mídia
-
-```javascript
-function getViewOnceMedia(msg) {
-  const inner =
-    msg.message?.viewOnceMessageV2?.message ||
-    msg.message?.viewOnceMessage?.message ||
-    msg.message?.viewOnceMessageV2Extension?.message
-
-  if (!inner) return null
-
-  if (inner.imageMessage) return { type: 'image', media: inner.imageMessage }
-  if (inner.videoMessage) return { type: 'video', media: inner.videoMessage }
-  if (inner.audioMessage) return { type: 'audio', media: inner.audioMessage }
-
-  return null
-}
-
-// Uso:
-const media = getViewOnceMedia(msg)
-if (media) {
-  console.log(`View-once ${media.type}`)
-  console.log('URL:', media.media.url)
-  console.log('DirectPath:', media.media.directPath)
-  console.log('MediaKey:', media.media.mediaKey) // necessário para download
-}
-```
-
----
-
-## 4. Como Exibir numa Ferramenta (Frontend/CRM)
-
-### 4.1 Lógica de detecção e exibição
-
-```javascript
-function renderMessage(msg) {
-  if (!isViewOnce(msg)) {
-    // Renderizar mensagem normal
-    return renderNormalMessage(msg)
-  }
-
-  const media = getViewOnceMedia(msg)
-  if (!media) return
-
-  // Verificar se já foi aberta (controle local da ferramenta)
-  const alreadyOpened = localStorage.getItem(`vo_${msg.key.id}`)
-
-  if (alreadyOpened) {
-    // Mostrar placeholder de "já visualizado"
-    return renderViewOncePlaceholder(media.type, msg.key.fromMe)
-  }
-
-  if (msg.key.fromMe) {
-    // Mensagem enviada por mim — nunca mostrar conteúdo
-    return renderSentViewOnce(media.type)
-  }
-
-  // Mensagem recebida — mostrar botão para "abrir uma vez"
-  return renderViewOnceButton(media.type, msg)
-}
-```
-
-### 4.2 Componente de exibição — mensagem recebida
-
-```javascript
-function renderViewOnceButton(type, msg) {
-  const icons = { image: '📷', video: '🎥', audio: '🎵' }
-  const labels = { image: 'Foto', video: 'Vídeo', áudio: 'Áudio' }
-
-  return `
-    <div class="view-once-bubble received">
-      <span class="view-once-icon">${icons[type]}</span>
-      <span class="view-once-label">${labels[type]} de visualização única</span>
-      <button onclick="openViewOnce('${msg.key.id}', '${type}')">
-        Abrir
-      </button>
-    </div>
-  `
-}
-
-async function openViewOnce(msgId, type) {
-  // 1. Marcar como aberta ANTES de mostrar (só uma chance)
-  localStorage.setItem(`vo_${msgId}`, '1')
-
-  // 2. Baixar e mostrar a mídia
-  const mediaUrl = await downloadViewOnceMedia(msgId)
-  showMedia(type, mediaUrl)
-
-  // 3. Após fechar/visualizar, substituir pelo placeholder
-  onMediaClosed(() => {
-    replaceWithPlaceholder(msgId, type)
-  })
-}
-```
-
-### 4.3 Componente de exibição — mensagem enviada
-
-```javascript
-function renderSentViewOnce(type) {
-  const labels = { image: 'Foto', video: 'Vídeo', audio: 'Áudio' }
-  return `
-    <div class="view-once-bubble sent">
-      <span class="view-once-icon">👁️</span>
-      <span>${labels[type]} de visualização única</span>
-      <span class="view-once-status">Enviada</span>
-    </div>
-  `
-}
-```
-
-### 4.4 Placeholder após visualização
-
-```javascript
-function renderViewOncePlaceholder(type, fromMe) {
-  const labels = { image: 'foto', video: 'vídeo', audio: 'áudio' }
-  const text = fromMe
-    ? `Você enviou uma ${labels[type]} de visualização única`
-    : `${labels[type]} de visualização única aberta`
-
-  return `
-    <div class="view-once-bubble placeholder">
-      <span class="view-once-icon">🚫</span>
-      <span>${text}</span>
-    </div>
-  `
-}
-```
-
-### 4.5 CSS sugerido
-
-```css
-.view-once-bubble {
-  display: flex;
-  align-items: center;
-  gap: 8px;
-  padding: 10px 14px;

-## 5. Código Implementado na API
-
-### 5.1 Geração da mensagem — `src/Utils/messages.ts`
-
-Quando `viewOnce: true` é passado, a mídia é encapsulada no wrapper moderno `viewOnceMessageV2` (campo 55 do proto) e o flag `viewOnce=true` é setado na mídia interna:
-
-```typescript
-if (hasOptionalProperty(message, 'viewOnce') && !!message.viewOnce) {
-    // Seta viewOnce=true na mensagem de mídia interna
-    if (m.imageMessage) m.imageMessage.viewOnce = true
-    else if (m.videoMessage) m.videoMessage.viewOnce = true
-    else if (m.audioMessage) m.audioMessage.viewOnce = true
-    // Usa viewOnceMessageV2 (campo 55) — formato atual do WA
-    m = { viewOnceMessageV2: { message: m } }
-}

-**Detecção de view-once real** (não confunde com botões/listas que também usam o wrapper `viewOnceMessage`):
-
-```typescript
-// Detecta view-once real pela flag viewOnce na mídia interna.
-// viewOnceMessage* wrappers são também usados por botões/listas/carrosséis
-// (que carregam interactiveMessage dentro) — esses NÃO têm viewOnce=true na mídia.
-const viewOnceInner =
-    message.viewOnceMessageV2?.message ||
-    message.viewOnceMessage?.message ||
-    message.viewOnceMessageV2Extension?.message
-const isViewOnceMsg = !!(
-    viewOnceInner?.imageMessage?.viewOnce ||
-    viewOnceInner?.videoMessage?.viewOnce ||
-    viewOnceInner?.audioMessage?.viewOnce
-)
-
-// Para view-once: DSM enviado apenas para o celular principal (device=0).
-// Companions (device>0) são omitidos — o servidor WA gera
-// <unavailable type="view_once"/> automaticamente para eles.
-const viewOnceMeRecipients = isViewOnceMsg
-    ? meRecipients.filter(jid => !jidDecode(jid)?.device)
-    : meRecipients
-
-// assertSessions apenas para quem vai realmente receber
-await assertSessions([...viewOnceMeRecipients, ...otherRecipients])
-
-const [meNodes, otherNodes] = await Promise.all([
-    createParticipantNodes(viewOnceMeRecipients, meMsg || message, extraAttrs),
-    createParticipantNodes(otherRecipients, message, extraAttrs)

-if (phashRecipients.length > 0) {
-    extraAttrs['phash'] = generateParticipantHashV2(phashRecipients)
-}
-```
-
-**`getMediaType()` — garante que vídeo e áudio view-once sejam entregues:**
-
-```typescript
-const getMediaType = (message: proto.IMessage) => {
-    // Desencapsula wrapper view-once antes de verificar o tipo de mídia.
-    // Sem isso, message.videoMessage e message.audioMessage são undefined
-    // (estão dentro do wrapper) e o atributo mediatype ficaria ausente no
-    // enc node — o servidor WA descarta silenciosamente vídeo/áudio view-once.
-    const inner =
-        message.viewOnceMessage?.message ||
-        message.viewOnceMessageV2?.message ||
-        message.viewOnceMessageV2Extension?.message
-    if (inner) {

-    }
-
-    if (message.imageMessage) return 'image'
-    else if (message.videoMessage) return 'video'
-    // ...
-}
-```
-
-### 5.3 Recepção — `src/Utils/decode-wa-message.ts`
-
-Quando a API recebe uma view-once como companion (linked device), o servidor envia dois stanzas:
-
-- **Stanza 1** (`enc`): conteúdo completo com metadados da mídia
-- **Stanza 2** (`unavailable type="view_once"`): sinal de sync
-
-O stanza 1 é detectado e marcado corretamente:
-
-```typescript
-// Detecta view-once na stanza 1 recebida por linked device.
-// O wrapper viewOnceMessage também é usado por mensagens interativas
-// (interactiveMessage, listMessage) — esses NÃO têm viewOnce=true na mídia.
-const viewOnceInner =
-    msg.viewOnceMessage?.message ||
-    msg.viewOnceMessageV2?.message ||
-    msg.viewOnceMessageV2Extension?.message
-if (
-    viewOnceInner?.imageMessage?.viewOnce ||
-    viewOnceInner?.videoMessage?.viewOnce ||
-    viewOnceInner?.audioMessage?.viewOnce
-) {
-    fullMessage.key.isViewOnce = true
-}
-```

-## 7. Limitações
-
-| Situação | Comportamento | Motivo |
-|---|---|---|
-| **Conta hosted (Meta Business Cloud API)** | **View-once bloqueado para todos os clientes** | **Política do servidor WA para contas hosted — sem workaround** |
-| WA Web do remetente | "Aguardando mensagem. Abra no celular." | Servidor WA só aceita `<unavailable>` vindo do celular principal, não de companions |
-| View-once de documento/sticker | Não suportado | Limitação do protocolo WA — só imagem, vídeo e áudio |
-| `error_479` nos logs | Normal, não é erro | TcToken é atualizado após o envio de view-once |
-| Companion não consegue abrir | Por design | O conteúdo não é entregue para linked devices |
-

-## 8. Checklist de Validação
-
-**Envio:**
-- [ ] Destinatário recebe com ícone de olhinho
-- [ ] Destinatário consegue abrir a mídia
-- [ ] Após abrir, a mídia some
-- [ ] Celular principal do remetente mostra "você enviou" com ícone de olhinho
-- [ ] WA Web do remetente mostra "Aguardando mensagem..."
-- [ ] Funciona para imagem, vídeo e áudio
-- [ ] Logs mostram `📤 Message sent` (error_479 é normal)
-
-**Recepção:**
-- [ ] Webhook recebe `key.isViewOnce = true`
-- [ ] `viewOnceMessageV2.message.imageMessage` (ou video/audio) está presente
-- [ ] API não crasha ao receber view-once de outro dispositivo
-- [ ] Mensagem interativa (botão/lista) enviada após view-once não é afetada

- * reissue that fired between history-sync chunks).

- * Why: the function does read-then-write merges (`keyStore.get('tctoken', ...)` →
- * compute → `keyStore.set(...)`) which are NOT atomic at the store level. If two
- * history-sync chunks invoke this concurrently (common during reconnect / QR
- * scan), an older chunk that started first can `keyStore.set` AFTER a newer
- * chunk, overwriting the newer entry — and worse, the merged `__index` write
- * can drop JIDs the other chunk just added. Result: stale tcTokens / repeat 463
- * sends until the next opportunistic refetch.
- *
- * Serialising via a chained Promise keeps the runs ordered while still freeing
- * the calling `processMessage` to emit `messaging-history.set` immediately
- * (the chain is fire-and-forget at the call site). Errors don't break the chain
- * — each `catch` resets it to `Promise.resolve()` so a single failure can't
- * stall future runs.
- *
- * The chain is module-scoped (one per Node process). Multiple Baileys instances
- * sharing this module will serialise across instances too, but their writes
- * target different keyStores so there's no correctness gain — only a tiny loss
- * of inter-instance parallelism for tcToken syncs, which is acceptable given
