Add README.md files for moeo/tutorial/Lesson{1-4}, smp/tutorial/Lesson{1-4},
and mo/tutorial/Lesson9 — these tutorials had no documentation.
Fix return 1 → return 0 in 28 tutorial main() functions across mo/ and
smp/ that unconditionally returned failure status.

Dynamic island topology
Three islands start with a ring topology and switch to a complete topology after 10 seconds of computation.
Same QAP problem as Lessons 1-2.
Running
From the build/smp/tutorial/Lesson4 directory:
./lesson4_topology
How it works
A callback function registered with the islands triggers the topology change:
void changeTopo(IslandModel<Indi>* _model, AbstractTopology& _topo)
{
// ... after 10 seconds:
_model->setTopology(_topo);
}
The topology can be changed at runtime via model.setTopology(), so you
can implement adaptive communication patterns based on time, convergence,
or any other criterion.
