fix: warn when automation-profile add --update given but no existing profile

When the --update flag is provided to agents automation-profile add but no existing profile with the given name exists, the command now emits a clear warning message to the user before proceeding to create the new profile. This prevents silent no-ops and helps users understand that --update had no effect.

Added a new BDD scenario to automation_profile_cli.feature to verify the warning is displayed when --update is given for a non-existent profile.
