Full scenario example

The full scenario combines multiple roles and subsystems. It is useful after the small examples make sense.

Look for:

• examples/session_minimal.rs extended with several plugins or a preset group (see The session facade)
• examples/c_abi/full_demo.c

What it proves:

• broad API surfaces still build together
• multiple subsystems can coexist on one node
• event flow can be observed across a combined node
