feat: use LTS Node.js version for installation

- Replace hardcoded setup_24.x with setup_lts.x for Linux apt/dnf/yum
- Update Windows installer to use Node.js 22 LTS with dynamic version fetch
- Update install messages to reflect LTS instead of specific version
- Fixes: Node.js 24+ requirement causing installation failures on some systems
- Ensures latest LTS version (20.x, 22.x) is used instead of bleeding edge
