This reverts commit 46460d49c7 (#26171).
Pause the Node 24 requirement so existing SSH and WSL users are not
surprised by a host-runtime upgrade requirement in the next release.
This is a precautionary rollout hold requested to avoid near-term user
disruption, not a cancellation of the Node 24 transition.
Restore the prior Node 18 host minimum and companion build targets.
The previously shipped bundled Node 24 runtime and compatibility launcher
remain in place. Preserve the original change in a separate draft PR for
reintroduction after compatibility and rollout validation.
* feat(runtime): default to bundled Node 24 and require modern hosts
* Update SSH deployment expectations for Node 24 guidance
* Expect Node 24 in Windows runtime installation guidance
