fix(sticker): address PR review — 8 fixes for security and correctness

- Gzip raw Lottie JSON to valid WAS format before emitting as .was
- Add decompression bomb protection (maxOutputLength: 50MB) in gunzipSync
- Fix Lottie validation: require both ip AND op fields (was OR)
- Validate isLottie override: throw on mismatch with detected format
- Fix compression to use resized webpBuffer (preserves 512x512 enforcement)
- Require Sharp for cover processing (remove broken WebP-in-PNG fallback)
- Update docs: tray icon is 96x96 PNG, thumbnail is 252x252 JPEG

-# 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

-  display: flex;
-  align-items: center;

-## 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 } }
-}
-```
-
-### 5.2 Envio — `src/Socket/messages-send.ts`
-
-**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)
-])
-participants.push(...meNodes)
-participants.push(...otherNodes)
-
-// phash recalculado com os participantes reais
-const phashRecipients = isViewOnceMsg
-    ? [...viewOnceMeRecipients, ...otherRecipients]
-    : [...meRecipients, ...otherRecipients]
-if (phashRecipients.length > 0) {
-    extraAttrs['phash'] = generateParticipantHashV2(phashRecipients)
-}
-```
-
-**`getMediaType()` — garante que vídeo e áudio view-once sejam entregues:**
-
-```typescript

-### 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

- * STRICTLY newer (`incoming > existing`). Equal timestamps are skipped to avoid
- * reverting senderTimestamp / realIssueTimestamp set by other layers (e.g. a
- * reissue that fired between history-sync chunks).
- *
- * Index hygiene: every JID we write here is added to the persistent prune index

- * 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
- * how rarely this runs vs. how rare cross-instance contention is.
