Updated automation_levels.feature to expect "applied" processing state
instead of "queued" after completing execute on a full_automation plan,
matching the new auto_progress() behavior that drives Apply to terminal
state.
Updated plan_cli_coverage_boost_steps.py to properly mock the full apply
lifecycle (get_plan → apply_plan → start_apply → complete_apply) instead
of returning a single plan from apply_plan, matching the updated
lifecycle_apply_plan command handler that now drives plans through to the
terminal applied state.
