Tom Boucher 7533cb4454 fix(#4104): park the prohibition-enforcement hang fixture on a settling timer (#4331) ...

* test(#4104): add self-exit regression for the hang fixture (RED at this sha)

* fix(#4104): park the hang fixture on a settling timer instead of a busy loop

The prohibition-enforcement hang fixture busy-looped `while (true) {}`, so a
worker orphaned by a killed runner burned a core forever. It now parks on a
10s settling setTimeout — still hung for any enforcement bound, ~0% CPU if
leaked, and guaranteed to self-terminate. A regression test spawns the exact
served body and asserts it self-exits with no signal.

* test(#4104): harden the self-exit regression (signal/spawn-error paths)

* changeset(#4104)

* changeset(#4104): backfill PR number
