Shield semantics: aiotools (deferred-edge) vs. asyncbis (level cancellation)

Companion experiments for the Async-SIG post comparing nested block-scoped shielding between aiotools' TaskScope and asyncbis' CancelScope/TaskGroup.

Scenario ported from aiotools' test_taskscope_shielded_nested_4 (timings scaled 1/10, wall-clock instead of VirtualClock).
