fix(build): restaurar targetSdk=35 perdido no bump da v0.2.2

Sem targetSdkVersion no manifest, o AGP usou minSdk (26) como alvo:
o instalador do Android 16 (One UI 8) bloqueia o APK como 'versão
antiga do Android'. Restore targetSdk=35 + versionCode 6 / 0.3.1.

Verificado em emulador Android 16 (API 36, Pixel 6): install sem
bloqueio, boot limpo, fluxo config -> lista -> status/busca/empty state.

   - editar offline → fila resiste à queda de rede → push automático ao restabelecer (`ConnectivityManager`);

     adota o servidor e o texto do Android vira exatamente **uma** cópia "… (conflito)"
     (idempotente; sincronizações serializadas por mutex + índices únicos na outbox).
-- Integração com a API: mesmos contratos do web client (`base_hash`/409, categorias, revisões).

 ## Roadmap honesto (não implementado aqui)
 
-- SSE (`/api/events`) no Android para push tempo-real em vez de gatilho pós-save (OkHttp SSE).
 - Token em Keystore/EncryptedSharedPreferences (hoje: sandbox do app via DataStore).
-- Editor WYSIWYG/realce de sintaxe mobile (fora do escopo "mais leve possível").
+- Sync reativo incremental (o pull compara hashes por nota; milhares de notas pediriam um
+  endpoint de delta no servidor).
 - Multi-perfil/servidores e sincronização de anexos.
