    CI: Cancel stale merge queue runs + use ubuntu-slim (#4106)
    
    CI: Cancel stale merge queue runs and move license check to ubuntu-slim
    
    A PR re-added to the merge queue reuses the same queue branch, so its
    runs waited behind the previous attempt's still-queued runs in the same
    concurrency group. Cancel in-progress runs for merge_group as well.
    
    Run the license check on ubuntu-slim to reduce demand for ubuntu-latest
    runners. That image has no Java, so install it explicitly.
