Pull request overview

This PR improves shutdown/cancellation behavior for SSH-based remote command execution by propagating OS signal cancellation through contexts and tuning how ssh subprocesses are terminated.

Changes:

• Customize os/exec.Cmd cancellation for OpenSSH runs by sending os.Interrupt and adding a WaitDelay.
• Update sendProfileCommand to use a signal-cancelled context for Connect/Run, while ensuring Close still runs with a non-cancelled context.

Reviewed changes

File	Description
ssh/openssh_client.go	Add custom exec cancellation behavior (SIGINT + wait delay) for OpenSSH command runs.
serve.go	Thread a signal-cancelled context into SSH Connect/Run and adjust Close to avoid cancellation interference.
