Fix forceKillAfter cleanup after non-zero process leader exit

[tim-smart]

Summary

Use terminateProcessGroup during scope release after a non-zero leader exit, so descendants that ignore SIGTERM are killed after forceKillAfter. The immediate best-effort exit listener is unchanged.

Includes the previously committed regression test; tests were unchanged during implementation.

Validation

• nix develop -c pnpm test --run packages/platform/node-shared/test/NodeChildProcessSpawner.test.ts (78 passed, including the regression)
• nix develop -c pnpm lint-fix
• nix develop -c pnpm check

Verified on Linux; macOS was not available. The process-group regression is skipped on Windows.

Closes EFF-1698
Closes #8338
