[Feature Idea] SSH Remote Execution

[albertalef]

Problem: Running commands on remote servers requires manually constructing SSH command strings, losing the clean RubyShell syntax and making deployment scripts verbose.

Solution: Add sh.remote to execute RubyShell blocks on remote servers via SSH, bringing the same familiar syntax to remote administration.

sh.remote("user@server") do
  ls("-la")
  cat("/etc/hostname")
end

sh.remote("deploy@production", port: 2222) do
  cd("/var/www/app")
  git("pull", "origin", "main")
  bundle("install")
  systemctl("restart", "app")
end

%w[web1 web2 web3].each do |server|
  sh.remote("admin@#{server}.example.com") do
    apt("update")
  end
end
