v1.93.28.0 fix(flaky): cso-snapshot-state resumes a paused contender only once it has stopped (GSTA-199) (#3716)

* fix(flaky): cso-snapshot-state resumes a paused contender only once ps shows it stopped (GSTA-199)

Co-authored-by: capy-ai[bot] <230910855+capy-ai[bot]@users.noreply.github.com>

* fix: pre-landing review fixes

resumeStopped checks for an exited child before reading ps and names that
exit in its error, separately from the 2 s never-stopped timeout.

* fix: resumeStopped reads /proc on Linux, keeps ps for macOS

The stop check no longer needs a ps binary on Linux. A missing /proc entry
(the child was already reaped) loops to the exit check instead of failing.

 # Changelog
 
+## [1.93.28.0] - 2026-11-03
+
+**`test/cso-snapshot-state.test.ts` no longer hangs when a paused contender is resumed too early.**
+
+### Fixed
+- The five paused-contender tests resume a child only once the process table shows it stopped (`/proc/<pid>/stat` on Linux, `ps` on macOS). Each child marks its pause and then stops itself in two steps, and a SIGCONT that arrived between the two did nothing, so the child stayed stopped and the test timed out (Free Tests 41117003351). With a 200 ms delay injected between the two steps, main failed 3 and then 5 of the 5 tests across two runs, and this change passed 5 of 5 both times. A child that exits, or never stops within 2 s, now fails with a named error instead of hanging. Timing bounds are unchanged.
+
 ## [1.93.27.0] - 2026-11-02
 
 **A test can keep an old value on purpose without turning off `literals` (#3490).** When a minimum version goes up, the test that checks the old version is refused has to keep the old value, and pregate failed it with `PREGATE_LITERALS`. The only way out was `warn: ["literals"]`, which turns the check off for every constant. Now that one line can carry `// pregate-literal: NAME=<old value> <reason>`.
