Wait for inherited stdio close in NodeChildProcessSpawner release and kill

[xia-chao]

Summary

NodeChildProcessSpawner already signals the process group on scoped release and kill, but it waited on the leader's exit. On Linux, shell: true uses dash (sh -c), which does not exec the command. SIGTERM kills the shell immediately, exit fires, forceKillAfter is dropped, and descendants keep running.

Release and kill now wait for the Node close event (inherited stdio released). Public exitCode / isRunning still use exit.

Fixes #7821

Test plan

• vitest --run packages/platform/node-shared/test/NodeChildProcessSpawner.test.ts
• Linux shell: true scope close does not return until the wrapper and its inherited-stdio child have printed *:SIGTERM
• macOS (bash execs) still completes the same wait
• exitCode / isRunning remain bound to the leader exit event
