Eric Traut 8960c363c6 Preserve installer stderr when releasing the install lock (#59227) ...

## Why

Redirecting stderr on `exec` while closing the lock descriptor suppressed subsequent installer warnings, including the warning that an existing npm-managed Codex installation remains installed.

## What changed

Remove the stderr redirection from `release_install_lock` when closing file descriptor 9. Add a regression test asserting that a noninteractive install succeeds and emits the existing npm installation warning.
