enableDrivers()

template<Bus... Buses>

void fl::enableDrivers ( )

inline

Register the named drivers with ChannelManager for runtime selection.

Each named bus's BusTraits<B>::registerWithManager() is invoked, which:

1. Lazily constructs the driver singleton (links its translation unit).
2. Calls ChannelManager::addDriver(priority, instance) so the runtime manager can route channels to it.

Pre-condition: the per-driver bus_traits.h for each B named here must be reachable from the calling translation unit. Including the per-platform driver headers brings the relevant specializations in. Naming a Bus whose BusTraits<B> specialization is not visible produces a clear "implicit instantiation of undefined template" diagnostic.
