v1.92.71.0 test(free): end four non-subject waits early and drop a duplicated test block (GSTA-151 D) (#3582)

* test(free): end four non-subject waits early and drop a duplicated test block

setup's _wait_with_deadline polls every 0.1 s on the SECONDS clock; pregate-supervise and gstack-detach wait on pids and go-files instead of fixed sleeps; qa-probe-gates loses its duplicated C2 block; context-identity runs one restore.

* test(setup): mark the sub-second wait bound as the contract (gstack-timing-ok)
