Pull request overview

This PR introduces a new SSHCoordinates interface (backed by the RPC proto) to centralize SSH connection parameters for creating SSHSessions, as groundwork for future VSOCK-based sessions. It refactors VM, daemon, CLI/GUI clients, and tests to use the new coordinates object rather than separate host/port/username/key fields.

Changes:

  • Adds SSHCoordinates to the RPC API and updates daemon/client code paths to use ssh_coordinates maps in SSHInfoReply.
  • Refactors PlainSSHSession, SSHClient, SFTPClient, and SFTPUtils to accept SSHCoordinates.
  • Updates VM backends/tests to provide ssh_coordinates() and switches SSH port types to uint32_t.
