El smoke-test contra prod revelo MongoDB 3.2.11 (EOL): el driver v6 exige >=4.2 y no conecta. Cambios: - mongodb ^3.7.4 + @types/mongodb; db.ts con useUnifiedTopology, sin retryWrites - sends.ts: deteccion de duplicate-key (11000) sin depender de MongoServerError - poller.ts: FilterQuery en vez de Filter - tests de integracion migrados de mongodb-memory-server a un fake en memoria (test/fake-repo.ts) porque no hay mongod 3.x ejecutable en hosts modernos; emula operadores ($ne/$in/$gte/$exists), $set/$unset e indice unico (11000) - docs: legacy-behavior.md §0 (entorno MongoDB 3.2, sin change streams -> fase 1b usara polling; recomendacion de upgrade de Mongo como fase propia) 47 tests en verde, typecheck y build OK. Datos reales del import: 413 pendientes FCM, 0 email, 8176 users con fireBaseToken.
