* Eliminates per-line `std::stringstream` buffer allocation in `sfst::ReadNGramList` by tokenizing lines with `absl::StrSplit` and `absl::string_view`. * Uses zero-copy string view lookup in `fst::SymbolTable::Find` and moves parsed n-gram vectors into the destination set. * Adds null pointer safety check for destination ngram_list.
