hariel1985 9292166223 Add safety guardrails for Force Kill and protected system processes

Security improvements:
- Force Kill (SIGKILL) now always requires confirmation - removed "Don't ask
  again" option for this destructive operation
- Added protection for critical system processes (kernel_task, launchd,
  WindowServer, loginwindow) - UI prevents force-killing these
- Terminate (SIGTERM) retains the "Don't ask again" option as it's a gentler
  operation that allows processes to save data

UX improvements:
- Clear error message when attempting to force-kill protected processes
- ConfirmationSheet now supports optional "Don't ask again" toggle via
  nullable skipPreferenceKey parameter

This prevents accidental system crashes from force-killing critical processes
while maintaining power-user convenience for regular termination.
