Replace std::vector<uint8_t> in recv_command_() with a member std::array<uint8_t, 36> buffer to eliminate heap allocation on every polling cycle. Also use pointer+length instead of vector references in handle_note_/handle_reply_, and use TextSensor's publish_state(const char*, size_t) overload to avoid temporary std::string construction for version and face name publishing.
