Helpers encode Tesla protobufs. You write the wrapped buffer over GATT.

1. Call CarServer::* or Security::* into a buffer.
2. Wrap with Session::BuildRoutableMessage on the matching domain.
3. Write the result. Reassemble the reply with BleFrame, then decode.

unsigned char action[256];
size_t action_size = 0;
TeslaBLE::CarServer::TurnOnClimate(action, &action_size);

unsigned char out[UniversalMessage_RoutableMessage_size];
size_t out_size = 0;
session.BuildRoutableMessage(
    UniversalMessage_Domain_DOMAIN_INFOTAINMENT,
    action,
    action_size,
    out,
    &out_size);

Lock, unlock, wake, trunks, and GetStatus use DOMAIN_VEHICLE_SECURITY and Security::*. Climate, charge, media, and GetVehicleData use DOMAIN_INFOTAINMENT and CarServer::*.
